This section explains the features and key functions of the SB-900.

• SB-900 features. B-2
• Main functions B-4

Features of the SB-900

The SB-900 is a high-performance CLS-compatible Speedlight with a large guide number of 34/48 (ISO 100/200, m) (111.5/157.5, ft.) (at the 35mm zoom position in Nikon FX format with standard illumination pattern, 20^ / 68^ .)

• Combined with a CLS-compatible camera, the SB-900 can easily perform various types of flash operations, such as i-TTL auto flash and wireless multiple flash (D-39).
• Three types of illumination patterns (standard, center-weighted and even) are available to match different shooting preferences.
• FX/DX selection enables the setting of the light distribution angle in accordance with the camera's image area between FX- and DX-formats, and provides effective and high-quality lighting.
• Power zoom function automatically adjusts the zoom position to match the lens focal length from 17 mm to 200 mm (in FX format)/12 mm to 200 mm (in DX format). When the built-in wide-flash adapter is used or the Nikon Diffusion Dome is attached, the zoom position is automatically set to match a wide-angle lens with much shorter focal length.
• Bounce flash (D-26) or close-up flash photography can be easily performed (D-30).
• Custom functions are provided to allow for various settings (C-20).

Compatible cameras

The SB-900 has been optimized for use with CLS-compatible SLR cameras.

• For usage with non-CLS-compatible SLR cameras and with i-TTL-compatible COOLPIX cameras, see "Using the SB-900 with non-CLS-compatible SLR cameras." (E-1)

CLS-compatible SLR cameras

D3, D700, D2 Series, D300, D200, D80, D70 Series, D60, D50, D40 Series, F6, etc.

i-TTL-compatible COOLPIX cameras

COOLPIX 8800, COOLPIX 8400, COOLPIX P5000, COOLPIX P5100, etc.

What is the Nikon Creative Lighting System (CLS)?

The SB-900 features the Nikon Creative Lighting System (CLS). This system offers additional flash shooting possibilities with digital cameras by taking advantage of your camera's digital communication capabilities. CLS is available when the SB-900 is used with compatible Nikon cameras.

The SB-900 offers these major features:

i-TTL mode

This is a Nikon Creative Lighting System TTL auto flash mode. Monitor pre-flashes are fired at all times. The subject is correctly exposed by the light from the flash lighting and the exposure is less affected by ambient light (R D-2).

Advanced Wireless Lighting

With Advanced Wireless Lighting, wireless multiple flash operation in the TTL (i-TTL) mode can be accomplished with CLS-compatible digital SLRs. In this mode, you can divide the remote flash units into three groups and control the flash output independently for each group, expanding your range of creative multiple-flash shooting techniques (D-43).

FV Lock (Flash Value Lock)

Flash Value, or "FV," is the amount of flash exposure for the subject. Using FV Lock with compatible cameras, you can lock in the appropriate flash exposure for the main subject. This flash exposure is locked in, even if you change the aperture or composition, or zoom the lens in and out. (D-55).

■ Flash Color Information Communication

When the SB-900 is used with compatible digital SLRs, color temperature information is automatically transmitted to the camera. In this way, the camera's white balance is automatically adjusted to give you the correct color temperature when taking photographs with the SB-900.

Auto FP High-Speed Sync

High-Speed flash synchronization at a compatible camera's highest shutter speed is possible. This is useful when you want to use a wider aperture to achieve shallow depth of field to blur the background (D-55).

AF-Assist illuminator

In autofocus operation, the SB-900 emits AF-Assist illumination, which matches the wider AF area of CLS-compatible cameras. With cameras supporting this function, autofocus photography in dim lighting is possible even when the camera's focus point (focus area) is changed (D-58).

Flash modes and functions on the SB-900

i-TTL mode (D-2)

The camera controls the SB SB-900's flash output level by measuring the light reflected from the subject when the SB-900 fires a series of monitor pre-flashes.

Auto-Aperture flash mode (D-5)

The SB-900 controls the flash output level by measuring the flash illumination reflected back from the subject using the sensor for Non-TTL auto flash and combining this with information from the camera, such as the ISO sensitivity and the aperture setting.

Non-TTL Auto flash mode (D-8)

The SB-900 controls the flash output level by measuring the flash illumination reflected back from the subject using the sensor for Non-TTL auto flash.

Distance Priority manual flash mode (D-11)

If you preset the aperture and the distance to the subject, the SB SB-900 will automatically take control of correct light output.

Manual flash mode (D-14)

By setting the aperture and the flash output level, you can manually set the exposure and the distance to the subject.

Repeating flash mode (D-17)

The SB-900 fires repeatedly to create stroboscopic multiple-exposure effects. This operation is useful when shooting fast-moving subjects.

ching illumination pattern (D-24)

You can select one of three types of illumination pattern (standard, center-weighted and even) in accordance with your objective.

Bounce flash

D-26)

By tilting or rotating the flash head, you can bounce the light off a ceiling or wall to make use of reflected light.

Close-up flash photography (D-30)

Close up flash photography can be achieved with use of the built-in wide-flash adapter and the flash head tilted down.

Using color filters

(D-33)

You can compensate for the color of a light source or create interesting effects by changing the light from the filters to a different color.

Flash output level compensation/Exposure compensation

Flash output level compensation is performed by modifying the flash output level for the flash illuminated subject only. Exposure compensation is performed by intentionally modifying the correct exposure to modify both the subject and background exposure.

Wireless multiple flash (D-39)

• Advanced Wireless Lighting (D-43)
  In this mode, you can divide the remote flash units into three groups and set the flash mode and flash output level compensation values separately for each group as well as the master flash unit.
  SU-4-type wireless multiple flash (D-50)

You can perform SU-4 type wireless multiple flash in two ways: in which the wireless remote flash units start and stop firing in sync with the master flash unit, and in which the remote flash units only start firing in sync with the master.

Functions that are set on the camera

FP Auto FP High-Speed Sync (D-55)

The SB-900 automatically fires at faster shutter speeds than the camera's sync shutter speed.

FV Lock (Flash Value Lock) (D-55)

Since it is possible to lock in the flash exposure level for the subject, you can alter picture composition while keeping the brightness of the subject constant.

Slow-Sync (D-55)

The flash is controlled at a slow shutter speed to obtain the correct exposure for both the main subject and background in low-light situations.

Red-Eye Reduction flash mode/Red-Eye Reduction Slow-Sync (D-56)

Red-eye effect, which causes the subject's eyes to appear red in color photographs, is reduced.

Rear-Curtain flash sync (D-56)

Rear-curtain flash sync creates a picture in which the blur of a moving subject appears behind the subject and not in front. In this mode, the flash fires just before the rear curtain starts to close.

Support functions

Power zoom function (D-57)

Automatically adjusts the zoom position to match the lens focal length.

Setting the ISO sensitivity (D-60)

The ISO sensitivity is automatically set based on information from the camera.

AF-Assist illuminator (D-58)

This enables you to perform autofocus flash photography when there is not enough light for normal autofocus operation.

Test firing

You can verify whether the subject will receive the correct exposure by test firing the SB-900.

Modeling illuminator (D-61)

Before actually shooting you can check the illumination and the shadows cast on the subject.

FX/DX selection (D-62)

The SB-900 automatically selects the suitable light distribution angle, in accordance with the camera's image area (between FX-format (36 x 24) and DX-format (24 x 16)).

- If the desired shooting distance is not on the chart, select a shorter shooting distance (e.g. when your desired shooting distance is 2.7m , select 2.5m ).

When the flash head is rotated in Distance-priority manual flash mode

• When the flash head is rotated to other than the horizontal/front or bounce-down flash position in Distance-priority manual flash, the flash mode is automatically changed to Auto aperture flash mode or Non-TTL auto flash mode.
• In this case, when the flash head is adjusted to horizontal/front or bounce-down flash position again, the flash mode is automatically changed to Distance-priority manual flash mode.

Insufficient light for correct exposure

• When the SB-900 fires at full flash output level, ready-lights on the SB-900 and in the camera's viewfinder blink for approximately three seconds after shooting.
• In this case, underexposure may occur. To compensate, use a wider aperture or move closer to the subject and reshoot.

Manual mode

In Manual flash mode, you select the aperture and flash output level. In this way, you can control the exposure and flash shooting distance when shooting subjects where the correct exposure is difficult to obtain in the TTL or Non-TTL auto flash mode.

• The flash output level can be set from M1/1 (full output) to M1/128 to match your creative preferences.
• Underexposure is not indicated in Manual mode.

Repeating flash

In Repeating flash mode, the SB-900 fires repeatedly during a single exposure, creating stroboscopic multiple-exposure effects. This operation is useful when shooting fast-moving subjects.

• Be sure to use fresh or fully charged batteries and allow enough time for the flash to recycle between each repeating flash session.
• Use of a tripod is recommended to prevent camera/flash shake, because slower shutter speeds are used.
• Underexposure is not indicated in Repeating flash mode.

Setting the flash output level, the number of repeating flashes, and the frequency (Hz) per frame

• The number of flashes (Times) represents the number of times the flash fires per frame.
• The frequency (Hz) represents the number of times the flash fires per second.
• The number of flashes is the maximum flash firing number. Because the Speedlight fires during a single exposure, the actual number of repeating flashes per frame falls below the one set as the shutter speed increases or the number of flashes per second decreases.
• Referring to the table below, set the flash output level, the frequency, and the number of repeating flashes separately for each picture.

Set the shutter speed.

• Use the following equation to determine the shutter speed and use a shutter speed one or more steps slower than the calculated shutter speed.

Shutter speed = Number of flashes per frame ÷ Frequency of flashes (Hz)

• For example, if the number of flashes per frame is 10 and the frequency is 5Hz , divide 10 by 5 to get a shutter speed of 2 seconds or slower. (Set shutter speeds of slower than 2 seconds.)
• B (bulb) can be used for the shutter speed.

7Compose the picture, confirm that the ready-light is on, then shoot.

Making sure the flash fires correctly before shooting

1 Confirm the test firing indicator appears on the LCD.
2 Confirm all shooting settings on the SB-900 and the camera are the same as for actual shooting, and then press the test firing button.

• Pressing the test firing button fires the flash for the selected frequency and number of flashes.

V Exposure compensation in Repeating flash mode

• The flash shooting distance calculated in Step ⑤ is the correct exposure for the first flash in the sequence. Therefore, repeating flash at this flash output level will result in overexposure of any overlapping images.
• To prevent this, set a smaller aperture on the camera as needed.

When the aperture value is not displayed in the SB-900's LCD

• Camera's aperture data is not transmitted to the SB-900.
• Press the Function button 3 for one second to highlight f-number and set appropriate aperture value on the SB-900.

Determining the aperture, flash output level and shooting distance

In Distance-priority, Manual and Repeating flash modes, use the guide number table and the following equation to calculate the aperture, flash output level, and shooting distance to obtain the correct exposure.

• The guide number (GN at ISO 100; m/ft) indicates the amount of light generated by the flash.
• The larger the number, the greater the flash output.

ISO sensitivity factors

For sensitivities, multiply the guide number by the factors shown in the table below.

ISO	25	50	100	200	400	800	1600	3200	6400
Factors	0.5	0.71	1	1.4	2	2.8	4	5.6	8

Calculating the correct aperture

Determine the guide number by referring to the guide number table. The correct guide number depends on the flash output level and zoom position. Next, calculate the correct aperture by using the equation below. The correct aperture depends on ISO sensitivity and shooting distance (m/ft.).

f/stop (aperture) = Guide number (GN at ISO 100; m/ft.) × ISO sensitivity factor ÷ Shooting distance (m/ft)

For example, for an ISO sensitivity of 400 (or ISO sensitivity factor: 2), with the zoom position adjusted to 28mm , and the flash output level set to M1/1:

Referring to the guide number table, determine the guide number as 30/98.4 (m/ft.).

When the shooting distance is 4m (13.1 ft.), the correct aperture value is:

30/98.4 (GN at ISO 100, m/ft) × 2 (ISO sensitivity factor for ISO 400) ÷ 4/13.1 (shooting distance; m/ft.) = 15 (aperture)

• Set the smaller aperture value (larger f-number) than calculated above on the camera.

Obtaining the correct flash output level

When the shooting distance and aperture are fixed, calculate the guide number (GN at ISO 100; m/ft.) by using the equation below, based on shooting distance and aperture:

Guide number (GN at ISO 100; m/ft.) = Shooting distance (m/ft) × Aperture (f/) ÷ ISO sensitivity factor

Referring to the guide number table, determine an appropriate flash output level corresponding to the guide number obtained above, then set the same value on the SB-900. For example, for the shooting distance of 6m (19.7 ft) with an aperture of f/8 and the ISO sensitivity of 400 (ISO sensitivity factor: 2):

6/19.7 (shooting distance; m/ft.) × 8 (aperture value) ÷ 2 (ISO sensitivity factor of ISO 400) = 24/79 (GN at ISO 100; m/ft.)

• When the zoom position is adjusted to 35~mm , set M1/2 flash output level on the SB-900, which can be obtained from GN 24/79 (m/ft.) corresponding to the zoom position of 35~mm referring to the guide number table.
• In Distance-priority manual flash operation, the correct flash output level is automatically determined by the SB-900 according to the shooting distance, aperture and ISO sensitivity that are set.

Calculating the shooting distance

Determine the guide number by referring to the guide number table. The correct guide number depends on the flash output level and zoom position. Next, calculate the shooting distance by using the equation below. The shooting distance (m/ft.) depends on ISO sensitivity and aperture.

Shooting distance (m / ft.) = Guide number (GN at ISO 100; m/ft.) × ISO sensitivity factor ÷ Aperture (f/)

Switching illumination pattern

In flash photography, the center of the image is most illuminated, while the edges are darker. The SB-900 provides three types of illumination patterns with different light falloff at edges. Select suitable type according to the shooting environment.

• For sample images of three types of illumination patterns, see the separate volume "A collection of example photos." Pp. 2-3

Standard

Center-weighted

Even

• The basic illumination pattern type for common flash shooting environment.

• To match the image circle of digital cameras, light falloff at the edge of image is less than shooting with existing external flash unit.

• The center-weighted pattern provides larger guide numbers at the center of the image than other illumination patterns at the same focal length (the light falloff at the edge will be greater than other illumination patterns).

• Suitable for shots, such as portraits, in which the light falloff at the edge of an image can be ignored.

• The light falloff at the edge of the image is less than with the standard illumination pattern.

• Suitable for shooting group photographs indoors, in which sufficient light is required without light falloff at the edges.

To set/confirm illumination pattern

The illumination pattern can be set using custom setting. (C-22)

• Standard is the default setting.
• The selected illumination pattern is indicated with an icon on the LCD.

Bounce flash operation

You can tilt or rotate the SB-900's flash head to bounce the light off the ceiling or walls, providing more natural-looking pictures of people with softer shadows. Also, you can soften the shadows even more by using the Nikon Diffusion Dome.

• For more details and comparative example photos, see the separate booklet, "A collection of example photos" Pp. 4-9.

Setting the flash head

Tilt or rotate the SB-900's flash head by holding down the flash head tilting/rotating lock release button.

• The SB-900's flash head tilts up 90^ and down -7^ , and rotates horizontally 180^ to the left and right.
• Set the flash head at a click stop at the angles shown.

Setting flash head tilting/rotating angles, and choosing the reflecting surface

• Good results are generally obtained most simply when the flash head is tilted up and you use the ceiling as a reflecting surface.
• Rotate the flash head horizontally to get the same effect when you hold the camera in the vertical position.
  Take care not to let light from the flash unit illuminate the subject directly.
• The effective distance between the flash

head and the reflecting surface is approx. 1 m (3.3 ft.) to 2 m (6.6 ft.) depending on the shooting conditions.

• In color photography, select white or highly reflective surfaces to bounce the light off of. Otherwise, your pictures will come out with an unnatural color cast similar to that of the reflecting surface.

Bounce flash operation

Camera's control panel

Setting the camera's exposure mode and metering system.

• Set the exposure mode to Aperture-Priority Auto (A) or Manual (M).
• Set the metering system to Matrix Metering "O" or Center-Weighted Metering "O".

Setting the SB-900's flash mode.

• Set the flash mode to i-TTL, Auto Aperture, or Non-TTL auto.

Setting the camera's aperture.

• In bounce flash, use an aperture 2 to 3 stops wider than with normal flash photography, and adjust it according to the results.
• In Non-TTL auto flash, set the same aperture on the SB-900 as is set on the camera.
• In Manual exposure mode, set the shutter speed.

Adjust the flash head and shoot.

Setting the aperture in bounce flash operation

• In bounce flash, there is a light loss of 2 to 3 stops when compared with normal flash photography (with flash head adjusted to horizontal/front). Therefore, you should use a two- or three-step wider aperture (small f-number), and adjust it according to the results.
• When the flash head is adjusted to other than the horizontal/front position, the flash shooting distance range indicator on the SB-900 disappears. To ensure correct exposure, first confirm the flash shooting distance range and aperture with the flash head in the normal position. Next, set this aperture on the camera.

Using the built-in bounce card

• In bounce flash photography, use the SB-900's built-in bounce card to create a highlight in the subject's eyes, making the eyes look more vibrant and avoiding illuminating the front of the subject.
• Tilt the flash head up 90^ to use this feature most effectively.

Setting the built-in bounce card

Pull out the bounce card and the wide-flash adapter and, while holding the bounce card, slide the wide-flash adapter back into place inside the flash head.

• To insert the bounce card, pull out the wide-flash card again and slide both cards together back into place.

Shooting with the Nikon Diffusion Dome

• By attaching the provided Nikon Diffusion Dome over the flash head, you can diffuse the light even more when doing bounce flash, creating extremely soft light with virtually no shadows.
• With the camera in either the horizontal or vertical position, you get the same effect.
• Good results are generally obtained when the flash head is tilted up 60^ .
• When the Nikon Diffusion Dome is attached and when the camera's image area is set to FX format, the zoom position is automatically set at 12mm , 14mm or 17mm , and 8mm , 10mm or 11mm while setting the camera's image area to DX format.

Attaching the Nikon Diffusion Dome

Attach the Nikon Diffusion Dome as shown in the illustration with the Nikon logo facing up.

Notes when using the Nikon Diffusion Dome

• The distance between the camera and subject differs from the center of the frame to the periphery, so the peripheral area might not be sufficiently lit in some cases.

Taking close-up photographs with bounce-down flash

When the distance between the camera and subject is less than approx. 2 m (6.6 ft.), you can take more natural-looking close-up pictures using the wide-flash adapter.

• Be careful when using a long lens that the light from the flash is not obstructed by the lens barrel.
• Vignetting may occur in close-up flash photography due to the illumination pattern, lens in use, focal length setting, etc. Therefore, make test shots before shooting an important assignment.
• When the SB-900 is attached to the camera and used as the only flash unit, tilting down the flash head is recommended to ensure sufficient illumination of the lower portion of the subject in close-up photography.
• A bounce-down icon appears when the flash head is tilted down.

Setting the built-in wide-flash adapter

Slowly pull out the wide-flash adapter all the way, and position it over the flash head.

Then slide the bounce card back into place inside the flash head.

• When the built-in wide-flash adapter is attached and when the camera's image area is set to FX format, the zoom position is automatically set at 12mm , 14mm or 17mm , and 8mm , 10mm or 11mm while setting the camera's image area to DX format.
• To set the zoom position manually, go to custom setting and set "Zoom position setting if the built-in wide-flash adapter is broken off accidentally" to [ON] (manual setting is available). (C-25)
• To put the built-in wide-flash adapter back into place, lift it and push it into the flash head as far as it will go.

Taking close-ups with bounce-down flash

Camera's control panel

Setting the camera's exposure mode and metering mode.

• Set the exposure mode to Aperture-Priority Auto (A) or Manual (M).
• Set the metering mode to Matrix Metering "O" or Center-Weighted Metering "O".

Set the SB-900's flash mode.

Position the built-in wide-flash adapter.

Tilt the flash head down.

Confirm the ready-light is on then shoot.

When shooting subjects closer than 0.6m (2 ft.)

• With the SB-900 attached to the camera, sufficient illumination of the subject cannot be obtained.
• In this case, use the SB-900 off-camera by attaching the optional TTL Remote Cord as shown below.
• When monitor pre-flashes are fired, distance information from the lens is used to determine the correct exposure. In this case, position the camera (A) and the SB-900 (B) at equal distances from the subject.

Use TTL Remote Code SC-29, SC-28 or SC-17.

Setting the aperture in off-camera close-up flash operation

• Calculate the aperture by using this equation and table.
• To ensure the correct exposure, use an aperture smaller (larger f-number) than the one obtained from the equation.

ISO sensitivity	100	200	400	800	1600	3200	6400
Factor (m/ft)	2/6.6	2.8/9.2	4/13	5.6/18	8/26.2	8/26.2	16/52.5

f/stop ≥ Factor ÷ Flash-to-subject distance

• For example, at an ISO sensitivity of 100 with a subject 0.5m (1.6 ft.) away and the wide-flash adapter in place, the suggested aperture is:

f / stop ≥ 2 ÷ 0.5 = 4 (in meters)

f / stop ≥ 6.6 ÷ 1.6 = approx.4 (in feet)

Notes on using a wideangle lens

• Generally, when using a wide-angle lens, the distance between the camera and subject differs from the center of the frame to the periphery, so the peripheral area might not be sufficiently lit in some cases.

Flash photography with color filters

Two types of color filters are supplied with the SB-900 for taking flash pictures under fluorescent lighting and for use with incandescent/tungsten lighting.

The optional Color Filter Set SJ-3 is available. (F-11)
- Four types of color filters for changing the color of the light from the flash are optionally available.
- For more details on photo examples with color balanced using color filters, see the separate booklet, "A collection of example photos" P. 10.

Using color filters

Filters	Purpose
Fluorescent filters (FL-G1, FL-G2)	Balance the color of light from the flash to match that of fluorescent lighting
Incandescent filters (TN-A1, TN-A2)	Balance the color of light from the flash to match that of incandescent or tungsten lighting
Color filters (Optional)	Create interesting effects by changing the color of the light from the filters

• Corresponding light source for each type of color compensation filter differs slightly. FL-G1 provides a greater compensation effect than FL-G2, and TN-A1, greater than TN-A2. Select the appropriate filter according to the results.

Notes on using color filters

• These filters are consumable items. When they fade in color or deteriorate, replace them with the backup filters provided.
• Do not use these filters when taking pictures with repeating flash, as the heat can damage them.
• The heat generated from the flash head can deform color filters. However, this will not affect their performance.
• Scratches on the filters will have no effect on performance unless the filters fade in color.
• To remove dust or dirt, wipe the filter lightly with a soft, clean cloth.

How to use color filters

1 Fold along the line marked on the color filter.
Attach the filter to the filter holder as shown in the diagram.

• Align the identification codes (silver marks) on the filter with the black portion on the holder.
• Insert the tip of the filter into the slit on the holder, then align the positioning hole on the filter with the projection on the holder.

V Attach the filter securely to the filter holder without creasing the filter or leaving any gaps.

Place the filter holder on the flash head with the Nikon logo facing up, as shown in the diagram, and insert into the slit at the top.

LCD indication while attaching an FL-G1 filter

Warning

4 Confirm the color filter indicator is displayed.

• Filter mounted and filter type indicators will be displayed.

• Do not block the filter detector window.

• If the warning shown in the figure in the left below appears on the LCD, the filter is not properly attached. Remove and reattach.

Balancing light from the flash using color filters

When using SB-900 with a camera equipped with filter detection (such as D3, D700)

• When a color filter is attached to the SB-900 while the camera's white balance is set to AUTO or FLASH, filter information is automatically transmitted to the camera, and the camera's optimum white balance is automatically adjusted to give the correct color temperature.

When using SB-900 with a camera not equipped with filter detection (such as D2 series, D300, D200, F6)

• Set the camera's white balance according to the filter in use.

■ White balance/exposure compensation value depends on camera in use

Flash output level compensation and exposure compensation

Making flash output level compensation

You can make exposure compensation for the flash illuminated subject only without affecting the background exposure by modifying the SB-900's flash output level.

• As a basic guide, some plus compensation may be necessary to make the main subject brighter, and some minus compensation to make it darker.
• Flash output level compensation is possible in i-TTL auto flash, Auto Aperture flash, Non-TTL auto flash and Distance-priority manual flash modes.

Press the Function button 1 to highlight the Flash output level compensation value.
Turn the selector dial to set desired flash output level compensation value.

• The compensation value can be set in 1/3 steps from +3.0 to -3.0 EV.

Press the [OK] button.

V Canceling flash output level compensation

• To cancel, turn the selector dial to return the compensation value to "0".
• The flash output level compensation cannot be canceled by turning the SB-900 off.

For cameras with a built-in flash featuring the exposure compensation function

• You can also set the flash output level on the camera. For details, see your camera user's manual.
• If you compensate the flash output level on both the camera and the SB-900, the exposure is modified by the sum total of both compensation values.
• In this case, the SB-900's LCD panel shows only the compensation value set on the SB-900.

Making exposure compensation

Exposure compensation allows you to make both the subject and background brighter or darker by intentionally modifying the correct flash exposure. This is useful when a subject of extremely high or low reflectivity is included in the scene or when you want to create flash photographs to match your creative preferences.

• Some plus compensation may be necessary when the background includes a highly reflective surface. Likewise, some minus compensation may be required when the background is dark or includes subjects of low reflectivity.

In i-TTL and Auto Aperture flash mode

• Make exposure compensation on the camera. For more details, see your camera user's manual.

In Non-TTL auto flash and Manual flash mode

• In the Non-TTL auto flash mode, the correct exposure can be obtained when the same aperture is set on the camera as that set on the SB-900. Therefore, to make exposure compensation, vary the aperture set on the camera while retaining the aperture set on the SB-900 or vice versa.
• In the Manual flash mode, calculate the proper aperture for the correct exposure from the guide number and the shooting distance (D-22). Then, use a larger or smaller aperture on the camera to make exposure compensation.
• As a basic guide, set a wider aperture on the camera or lens to make the main subject brighter or a smaller aperture to make it darker.

Wireless multiple flash shooting

With the SB-900, the "Advanced" and "SU-4 type" wireless flash operations are available.

• The Advanced Wireless Lighting mode is automatically set as the default. Advanced Wireless Lighting is recommended for standard multiple flash photography.
• SU-4 type wireless multiple flash, set the wireless flash mode to "SU-4" in the custom setting. (C-22)

Flash shooting with Advanced Wireless Lighting

• Available when the SB-900 is used with CLS-compatible cameras.
• Compatible with i-TTL flash mode.
• In this mode, you can divide the remote flash units into three groups and set the flash mode and flash output level compensation values separately for each group.

SU-4 type wireless multiple flash shooting

• SU-4 type wireless multiple flash is particularly suitable for shooting fast moving subjects as both the master flash unit and remote flash units fire simultaneously.
• There are no restrictions as to which cameras can be used.
• Speedlight featuring wireless multiple flash capability can be used either as the master or remote flash unit.
• Speedlights compatible with TTL auto flash can be used as the master flash unit. The optional Wireless Slave Flash Controller SU-4 is necessary when you want to use these Speedlights as remote flash units.
• The camera's built-in flash can also be used as a master flash unit.

Master flash unit and remote flash unit(s)

In this user's manual, a flash unit mounted on the camera, the camera's built-in flash, or the one directly connected to the camera via a TTL Remote Cord is called the master flash unit. All other flash units are called remote flash units.

Notes on performing wireless multiple flash photography

• To avoid accidental firing, turn off the camera and all flash units before mounting the master flash unit on or connecting it to the camera.
• The master flash unit cannot be test-fired.
• The brightness of the flash illumination is inversely proportional to the square of the distance between the flash unit and the subject. For example, if the distance between Speedlight A and the subject is 1 m (3.3 ft.), and Speedlight B is 2 m (6.6 ft.) and both A and B have the same guide numbers, the combined brightness of the two Speedlights will be:
• A : B = 1 : 4 (in meters) or approx. 11:44 (in feet)
• See the instruction manuals of your cameras and Speedlights.

Notes on remote flash

Take care of the following.

Notes on setting a remote flash unit

• When using a Speedlight that has a standby function as a remote flash unit, make sure that the standby function is set to "OFF," or select a standby duration that is long enough in the custom setting.
• The standby function of the SB-900, SB-800, SB-600 and SB-80DX is canceled when wireless remote flash mode is set. Make sure that there is sufficient battery power.
• The SB-50DX's standby duration is automatically extended to approx. one hour when it is set to wireless remote flash mode.
• Set the angle of coverage of the remote flash units wider than the picture angle, so that the subject will receive sufficient illumination even when the angle of the flash head is off axis from the subject. When the flash-to-subject distance is very short, set the angle of coverage wide enough to achieve sufficient light.

Notes on setting up the remote flash units

• In most cases, position the remote flash unit(s) closer to the subject than the camera, so that light from the master flash unit can reach the light sensor of the remote flash unit(s). This is particularly important when holding a remote flash unit in your hand.

• Data communication cannot be performed properly if there is an obstacle between the master unit and remote flash units.

• Take care not to let light from the remote flash unit enter the camera lens directly or indirectly in i-TTL auto flash mode. Also, prevent light from entering the master flash unit's light sensor window for Non-TTL auto flash (in Auto Aperture or Non-TTL auto flash mode). Otherwise, the correct exposure cannot be obtained.

• There is no limit to the number of remote flash units that can be used together. However, when using many remote flash units, light may be unintentionally picked up by the light sensor of the master flash unit and interfere with correct operation. The practical number of remote flash units for wireless multiple flash shooting are three. In Advanced Wireless Lighting, for practical purposes, the number of remote flash units should be limited to three for one group.
• Use the provided Speedlight Stand AS-21 for stable placement of the remote flash units.
• Be sure to perform test firing after setting up all flash units.

Using the Speedlight Stand

Use the provided Speedlight Stand AS-21 for stable placement of the remote flash units.

• Attach the SB-900 to the Speedlight Stand in the same way that you attach it to the camera's accessory shoe. The same is true when detaching it from the camera.
• Speedlights SB-15 and SB-27 cannot be used with the AS-21.

Confirming shooting situations in wireless multiple flash operation

You can confirm wireless multiple flash operation by checking the ready-light on the SB-900 or the sound monitor during and after shooting.

• When the SB-900 is used as a wireless remote flash unit, you can monitor its operation by listening to the sound monitor. This function can be activated or canceled using custom setting (C-24). This function is set to activate as the default.
• To save battery power, the ready-lights on the remote flash units can be turned off in the custom setting. The rear ready-light is set to light up and the front ready-light is set to blink as the default. (C-24)

Confirming flash operation using the ready-light or sound monitor

Ready-light of master flash unit	Ready-light of remote flash unit	Sound monitor	Speedlight condition
Lights up	The rear ready-light lights up and the front ready-light blinks.	One beep	Ready to fire
Lights up or does not come on (not blinking)	The rear ready-light lights up, and the front ready-light blinks or goes out.	Two short beeps	Fired properly
Blinks for approx. 3 sec.	Quickly blinks for approx. 3 sec.	Three long beeps for approx. 3 sec.	Both the master and remote flash units have fired at full output but light may have been insufficient for correct exposure. Use a wider aperture and reshoot.
Lights up or does not come on (not blinking)	Quickly blinks for approx. 3 sec.	Three long beeps for approx. 3 sec.	The light sensor of remote flash could not receive correctly the command light from master flash. The light sensor could not detect when to stop firing in sync with the master flash unit, because a strong reflection from the remote flash unit itself or light from another remote flash unit may have entered the light sensor window. Change the direction or position of the remote flash unit and reshoot.
Normal operation	Normal operation	Warning chime rings twice (when the SB-900 detects high temperature), or once (for each flash firing)	The SB-900's temperature has risen as a result of the flash being fired multiple times in quick succession. Wait until the SB-900 cools down.
Goes out	Goes out	Warning chime rings twice.	The SB-900's temperature has risen to a certain level and the SB-900 enters protective shutdown mode. Wait until the SB-900 cools down.

Flash shooting in Advanced Wireless Lighting

When the SB-900 is used with Nikon CLS-compatible cameras, Advanced Wireless Lighting is possible. In this mode, you can divide the remote flash units into three groups and set the flash mode and flash output level compensation values separately for each group as well as the master flash unit. This is defined as Flash Shooting in the Advanced Wireless Lighting.

To take photos with repeating flash, see custom setting. (C-22)
- For more details on the example photos in Advanced Wireless Lighting, see the separate booklet, "A collection of example photos" Pp. 16-19.

Mechanism of the Advanced Wireless Lighting

• Remote flash units can be set up to a maximum of three groups (A, B, C).
• Single or several remote flash units can be allocated for one group.
• For a total of four groups including the master and other remote flash units in three groups, you can set the flash mode and flash output level compensation values separately for each group.
• Select one of the four available channels through which the master and remote flash units exchange data.
• If another photographer uses the same type of wireless remote flash setup close by, your remote flash units may accidentally fire in sync with that photographer's master flash unit. To avoid this, use a different channel number.

Flash set-up in the Advanced Wireless Lighting

Arrange the master and remote flash units within the range as instructed in the illustration below.

• Direct the light sensor window of the remote flash units toward the master flash.
• As a basic guide, the effective shooting distance between the master and remote flash units is approx. 10m (33 ft.) or less in the front position, and approx. 7m (23 ft.) at both sides. These ranges vary slightly depending on the ambient light.
• Be sure to place all remote flash units that are set in the same group close together.
  See "Notes on the remote flash". (D-40)

Setting the SB-900 to Advanced Wireless Lighting

You can set the SB-900 to Advanced Wireless Lighting using the Power ON-OFF switch/wireless setting switch.

• Turn the switch while holding down the button on the center.

Commander function

• The "Commander function" enables the SB-900 to trigger remote flash units without firing itself. To activate the "Commander function," set the SB-900 as the master flash unit and set its flash mode to "Flash canceled."
• This operation will normally not affect the correct exposure of the subject, although the exposure might be affected if the subject is close and a high ISO sensitivity has been set. To limit this effect as much as possible, bounce the light by tilting or rotating the SB-900's flash head.
• Refer to "Commander mode" in your camera user's manual when using a camera's built-in flash as a master flash unit to trigger the remote flash unit (SB-900) in the commander mode.

Repeating flash shooting

In the Advanced Wireless Lighting, the repeating flash operation is possible.

• The Repeating flash mode can be activated or canceled using the custom setting. (C-22)

• In the repeating flash mode, all settings of flash output level, frequency and the number of repeating flashes per frame are common to both the master flash unit and remote flash units.
• Referring to "Repeating flash shooting", set the flash output level, frequency, and the number of repeating flashes per frame. (D-17)

SU-4 type wireless multiple flash shooting

SU-4 type wireless multiple flash is particularly suitable for shooting fast moving subjects as both the master flash unit and remote flash units fire simultaneously.

• SU-4 type wireless multiple flash can be performed in two ways: (1) In the AUTO (auto) mode, in which the wireless remote flash units start and stop firing in sync with the master flash unit, and (2) in the M (manual) mode, in which the wireless remote flash units only start firing in sync with the master flash unit.

Suitable cameras and Speedlights

Suitable cameras	Suitable master Speedlight	Suitable remote Speedlights
No limitation	• Speedlights compatible with Non-TTL auto, Distance-priority manual flash and manual flash and monitor pre-flashes that can be canceled in those modes • Camera's built-in flash with monitor pre-flashes that can be canceled.	• Speedlights compatible with SU-4 type wireless flash operation • Speedlights connected to the optional Wireless Slave Flash Controller SU-4.

  The flash output level can be set from M1/1 to M1/128.

SU-4 type wireless multiple flash shooting

Canceling monitor pre-flashes

In SU-4 type wireless multiple flash, cancel the monitor pre-flashes of the master flash unit, since monitor pre-flashes cause incorrect exposure.

• When the SB-900 is set as the master flash unit, monitor pre-flashes will not fire.
• For other Speedlights, be sure to cancel the master flash unit's monitor pre-flashes. For how to cancel the master flash unit's monitor pre-flashes, refer to the user's manual of each Nikon Speedlight.

Procedures for SU-4 type wireless multiple flash shooting

Camera's control panel

Remote flash unit's LCD panel

Master flash unit's LCD panel

1 Set the camera's exposure mode to A (Aperture-Priority Auto) or M (Manual).
2 Set up all Speedlights (both master and remote flash units) as the SU-4 type wireless multiple flash mode.
Set the flash mode of the remote flash units to AUTO (auto) or M (manual).
4 Set the flash mode of the master flash unit.

• Set it to Non-TTL auto, Distance-priority manual or Manual flash mode, when the remote flash units are set to AUTO (auto).
• Set it to Manual flash mode, when the remote flash units are set to M (manual).

⑤ Confirm the aperture, flash output level and flash shooting distance, then shoot.

To prevent the remote flash units from firing accidentally

With the SU-4 type wireless multiple flash, note the following:

• Do not leave the power of the remote flash units on. Otherwise, ambient electric noise due to a discharge of static electricity, or other electromagnetic wave, etc. may trigger them accidentally. Be sure to turn the power off.

Adjusting the flash output level of the remote flash units in the M (manual) mode

Adjusting the flash output level manually

• Use the following equation to determine the proper manual flash output level of the remote flash unit, depending on your creative preferences.

GN = F × D , where GN is the guide number of the remote flash unit (in meters/feet), F is the lens aperture in use, and D is the distance between the remote flash unit and the subject (in meters/feet).

For example, with the SB-900's zoom position adjusted to 18 mm, using an ISO sensitivity of 100, standard illumination pattern, in FX-format, shooting a subject at a distance of 2 m (6.6 ft.) with a lens aperture of f/5.6, then GN (in meters) = 5.6 × 2 = 11.2, or GN (in feet) = 5.6 × 6.6 = approx. 37. Therefore, to get the correct exposure, refer to the Guide Number table (F-19) and adjust the flash output level to M1/4.

• Refer to "Determining the aperture, flash output level and flash shooting distance in the Distance-priority manual and Manual flash mode" (D-22).

Adjusting the flash output level in Non-TTL auto flash (A); applicable when using a Speedlight compatible with Non-TTL auto flash mounted on the SU-4 (optional)

• Non-TTL auto flash (A) can also be selected on the remote flash unit. In this case, the remote flash unit controls the flash output based on the aperture and ISO sensitivity set on the remote flash unit, and automatically stops firing in sync with the master flash unit (D-8).

1 Set the same ISO sensitivity on the remote flash unit as set on your camera.
Set the same aperture on both the lens and the remote flash unit to obtain the correct exposure.

• Depending on your creative preferences, you can intentionally overexpose or underexpose the picture by modifying the aperture.
• The above setting is applicable only when both the master and remote flash units face the same direction.
  Refer to "Flash shooting distance range" (F-16) for more details.

Available functions to be set on the camera

The following functions are available when used with cameras so equipped. Set these functions on the camera. They cannot be set on the SB-900 directly.

• For detailed information regarding camera functions and settings, refer to your camera user's manual.

Auto FP High-Speed Sync mode

High-Speed flash synchronization at a compatible camera's highest shutter speed is possible.

• The Auto FP High-Speed Sync mode is automatically set when the shutter speed exceeds the camera's sync shutter speed.
• This is useful when you want to use a wider aperture to achieve shallow depth of field to blur the background without worrying about sync shutter speed.
• Auto FP High-Speed sync also operates in the Advanced Wireless Lighting mode.
• Available flash modes are i-TTL, Auto Aperture flash with monitor pre-flashes, Non-TTL auto flash with monitor pre-flashes, Distance-priority manual flash, and Manual flash when using a single flash unit.
• For flash shooting distance range in the TTL auto flash mode and the guide numbers in the Auto FP High-Speed Sync mode, refer to "Specifications."

■ Flash Value Lock (FV Lock)

Using FV Lock, you can lock in the appropriate flash exposure, while keeping the subject illumination constant even if you change the composition.

• The flash exposure (brightness) remains the same even when you change the aperture or zoom the lens in and out, because the flash output level automatically follows.
• It is possible to take up to a several number of frames during FV Lock operation.
• Available flash modes are i-TTL, Auto Aperture flash with monitor pre-flashes and Non-TTL auto flash with monitor pre-flashes.
• FV stands for Flash Value, meaning flash illuminated subject exposure.

Slow-sync flash

The flash is controlled at a slow shutter speed to obtain the correct exposure for both the main subject and background in low-light situations.

• Since slow shutter speeds are normally used, use of a tripod is recommended to prevent camera shake.
• For more details on the example photos, see the separate booklet, "A collection of example photos" Pp. 12-15.

Available functions to be set on the camera

Red-eye reduction/Red-eye reduction with slow-sync flash

To prevent your subject's eyes from appearing red in color pictures shot in dim light, the SB-900 fires three flashes at reduced output just before the picture is taken.

• In the Red-eye reduction with slow sync flash, red-eye reduction is combined with slow-sync flash.
• Since slow shutter speeds are normally used in red-eye reduction with slow-sync flash, use of a tripod is recommended to prevent camera shake.

Rear-curtain sync

In normal flash photography, when shooting fast-moving subjects at slow shutter speeds, unnatural-looking pictures can occur, because the subject frozen by the flash appears behind or within the blurred movement (see photo below right).

Rear-curtain flash sync creates a picture in which the blur of a moving subject (for example, the taillights of a car) appears behind the subject and not in front.

• In front-curtain sync, the flash fires immediately after the front curtain opens completely; in rear-curtain sync, the flash fires just before the rear curtain starts to close.
• Since slow shutter speeds are usually used, use a tripod to prevent camera shake.
• This function does not operate in Repeating flash operation.
• In multiple flash, the master flash unit can be set to either front-curtain or rear-curtain sync flash. However, the remote units cannot be set to rear-curtain sync flash. (D-39)

Canceling the power zoom function

The power zoom function can be canceled in the custom setting. (C-23)

When the power zoom function is canceled

• The zoom-head can be manually adjusted, but the zoom position indicator does not change even if the lens is zoomed, a lens is changed, or the power turned on or off.
  An " appears on the LCD panel.
• See "Setting the zoom position manually" above for setting the zoom position.

AF-Assist Illuminator

When the light is too dim for normal autofocus operation, the SB-900's AF-Assist illuminator enables you to perform autofocus photography.

• The SB-900's AF-Assist Illuminator supports the dynamic-area AF system.
• You can set the SB-900's AF-Assist Illuminator to activate or cancel in the custom setting mode. (C-23)
• The AF-Assist Illuminator cannot be used with cameras not compatible with CLS and COOLPIX cameras.

Notes on using the AF-Assist Illuminator

• The AF-Assist Illuminator is available, if an AF lens is mounted and the camera's focus mode is set to S (Single Servo AF with focus priority), AF-A, or AF.
• The effective shooting distance with the AF-Assist Illuminator is approx. 1 m to 10m (3.3 to 33 ft.) from the center of the image with a 50mm f/1.8 lens. The shooting distance varies depending on the lens in use.
• With a D3 camera, for example:
• Suitable lens focal length is between 17mm and 135mm . Focus areas for each focal length, in which autofocusing is available, are as follows:

17 mm - 19 mm	20 mm - 105 mm	106 mm - 135 mm

• The AF-Assist illuminator will not light up, if the camera's autofocus is locked or the SB-900's ready-light does not come on.
  Refer to your camera user's manual for more information.

AF-assist illuminator/flash firing off

You can set the SB-900's AF-Assist Illuminator and flash firing to activate or cancel in the custom setting. (C-23)

Using the SB-900 off-camera

When using the SB-900 off-camera with the TTL Remote Cord SC-29, autofocus flash photography in dim light is possible, because the SC-29 features an AF-Assist illuminator function. (F-11)

For cameras having a built-in Speedlight

• Even when the camera's AF-assist illuminator is set to activate, the SB-900's AF-Assist illuminator is given priority and the camera's AF-Assist illuminator does not light up.
• The camera's AF-assist illuminator lights up only when the SB-900's AF-Assist illuminator is canceled.

Setting the ISO sensitivity

The ISO sensitivity is automatically set based on the information transmitted from the camera to the Speedlight.

Setting the ISO sensitivity manually

You can set the ISO sensitivity manually using the custom setting. (C-24)

• The available ISO sensitivity range is ISO 3 to 8000. Note that the ISO sensitivity set on the camera is given priority.

Test firing function

You can determine whether the subject will receive the correct exposure by test firing the SB-900 before actually taking the picture by pressing the [Test firing] button.

• The SB-900 fires at M1/128 flash output in the i-TTL flash mode. The amount of flash output can be modified in the custom setting. (C-23)
• In Auto Aperture/Non-TTL auto flash operations, the SB-900 fires at a flash output controlled by the aperture set.
• In the Manual mode, the SB-900 fires at the flash output value set.
• In wireless multiple flash photography, the SB-900 does not perform test firing if it is set as a master flash unit.

Microcomputer characteristics

The SB-900 incorporates a microcomputer to control flash operations. In rare cases, the SB-900 may not work properly even after fresh batteries are properly installed. If this happens, replace the batteries while the SB-900 is turned on.

Notes on continuous flash shooting

To prevent the SB-900 from overheating, allow the SB-900 to cool down for at least 10 minutes after the maximum number of continuous firings have been performed as shown in the table below.

• Setting the "Thermal Cut-out" function is recommended. (F-6)

Do not exceed the maximum number of continuous firings, as this may cause the SB-900 to overheat or degrade.

Maximum number of continuous firings

Flash mode	Max. number of continuous firings (at 6 frames/sec.)
i-TTL	15 or less
Non-TTL auto
Manual flash mode (flash output level: M1/1, M1/2)
Manual flash mode (flash output level: M1/4 to M1/128)	40 or less

Notes for battery temperature

While operating continuous flash shooting, batteries may also generate heat. When replacing batteries after continuous flash shooting, note not to get burned.

Thermal Cut-out

The SB-900 features thermal cut-out, which offers protection against raised operating temperature.

• This feature is controlled from the Custom Settings menu. (C-24)
• The selected setting is shown by an icon.

Thermal Cut-out: On

• The temperature of the SB-900 is shown in three stages.

  Operation can be resumed once the warning is no longer displayed.

Tips on Speedlight care

WARNING

Never use thinner, benzene, or other active agents when cleaning the Speedlight,

as this may damage the Speedlight or cause it to catch on fire. Using these agents may also impair your health.

Cleaning

• Use a blower brush to remove dirt and dust from the SB-900 and clean it with a soft, clean cloth. After using the SB-900 near saltwater, wipe the flash unit with a soft, clean cloth moistened slightly with plain water to remove the salt, then dry it using a dry cloth.
• On rare occasions, the LCD may turn on or go dark, due to static electricity. This is not a malfunction. The display will soon return to normal.
• Do not drop the SB-900 or hit it against a hard surface, as this may damage its precision mechanisms. Do not apply strong pressure to the LCD panel.

Storage

• Store the SB-900 in a cool, dry place to prevent malfunctions due to high humidity, as well as the growth of mold or mildew.
• Keep the SB-900 away from chemicals such as camphor or naphthalene. Avoid exposing the SB-900 to magnetic waves from TVs or radios.
• Do not use or leave the SB-900 in locations subject to high temperatures such as those encountered near a heater or stove, as this may cause damage.
• When not using the SB-900 for more than two weeks, be sure to remove the batteries to prevent malfunctions due to battery leakage.
• Take the SB-900 out once a month, insert the batteries, and fire the unit several times to reform the capacitor.

Operating location

• An extreme temperature change can cause condensation to form inside the SB-900. When subjecting the SB-900 to sudden and extreme temperature changes, place it inside an airtight container such as plastic bag. Leave it inside the container for a while before exposing it gradually to the outside temperature.
• Avoid exposing the SB-900 to strong magnetism or radio waves from TVs or high-voltage power transmission towers, as this may cause it to malfunction.

Suitable batteries

Use four AA-type batteries of any of the following types:

• Alkaline-manganese (1.5V) batteries
• Lithium (1.5V) batteries
  OxyrideTM (1.5V) batteries

• Ni-MH (1.2V) batteries

• High-power manganese batteries are not recommended.

• Depending on battery specifications, when batteries become hot, the SB-900's safety circuits are activated, cutting off power. This often occurs when the flash unit is operated in the repeating flash mode. Battery power will recover when the temperature returns to normal.
• Be sure to read the user's manuals for your rechargeable batteries and battery charger for detailed information on how to handle and recharge the batteries.
• Never attempt to charge batteries that are not rechargeable batteries, as they could explode.

Notes on handling batteries

• Because flash consumes a large amount of battery power, batteries may not operate properly before reaching the end of their stated lifespan or the number of charges/discharges as specified by the battery manufacturer.
• When replacing batteries, replace all four batteries at the same time. Do not mix battery types or brands or use old with new batteries.
• When installing batteries, turn off the power of the Speedlight and never reverse the polarity of the batteries.
• If the battery terminals become soiled, remove dirt and smudges before use, as this may cause malfunction.
• Battery power tends to weaken as the temperature drops. It also gradually decreases when batteries are not used for a long time and recovers after a short break following intensive use. Be sure to check battery power and replace the batteries with fresh ones if you notice any delays in the recycling time.
• Do not store batteries in locations subject to high temperatures and high humidity.

Ni-MH

Recyclingrechargeable batteries

To protect the environment, do not dispose of used rechargeable batteries yourself. Instead, take these batteries to your nearest recycling center.

About the LCD panel

Characteristics of the LCD panel

• Due to the directional characteristics of LCDs, the LCD panel is difficult to read when viewed from above. However, it can be seen clearly from a somewhat lower angle.
• The LCD panel becomes darker at high temperatures (approx. 60^ / 140^ ), but returns to normal at normal temperatures (20^ / 68^) .
• The LCD's response time slows down at low temperatures (approx. 5^ / 41^ and below), but returns to normal at normal temperatures (20^ / 68^) .

LCD panel illuminator ON/OFF

Press any button on the SB-900 to turn the illuminator on (when the SB-900 power is on) and make the LCD panel easier to read.

• The illuminator goes off if the SB-900 is not operated for 16 seconds.
• To cancel the LCD panel illumination, go to the custom setting (C-24) and turn it off.
• Even if the LCD panel illuminator is set to OFF, the SB-900's LCD panel illuminator turns on when the camera's control panel illuminator is turned on. The LCD panel illuminator also lights up when the custom setting is displayed.

• Guide numbers in tables above are for when the SB-900 is mounted to the D3 camera and with 1/500 sec. shutter speed.
• Guide number with Auto FP High-Speed Sync varies depending on the camera's shutter speed. For example, when the shutter speed is changed from 1/500 sec. to 1/1000 sec., the guide number decreases 1 EV. The faster the shutter speed, the smaller the guide number.
  BA: With the Nikon Diffusion Dome attached
• WP: With the wide-flash adapter in place
