How to adjust the white balance on the Canon EOS Rebel SL2?

Accepted Answer

To adjust the white balance on your Canon EOS Rebel SL2, follow these steps:

Steps

Press the WB (White Balance) button located at the back of the camera
Turn the main dial to select a preset setting suitable for your lighting conditions

Available Modes

Sunny: For shots in direct natural light
Cloudy: For overcast days or shade

For more precise control, select the manual measurement option, point the camera at a neutral white surface in your shooting environment, and then confirm with the SET button. This method ensures accurate color reproduction regardless of lighting conditions.

Question 2

Where is the internal battery to save the time and date on the Canon PowerShot SX70 HS?

Accepted Answer

The Canon PowerShot SX70 HS does not have a separate internal battery for saving the time and date. Unlike some DSLR or hybrid cameras that use a dedicated button cell (RTC battery), this compact model manages the clock solely through its main rechargeable battery.

How the time and date backup works: The date and time information you set when starting the device is retained in memory thanks to the continuous power supplied by the main battery. This data is used to timestamp your photos and videos during shooting.

Risks of losing settings: If the battery completely discharges or if you remove it for an extended period (several weeks or months), the camera may lose the date and time settings. Upon the next power-up, the [Date/Time/Zone] screen will automatically appear to prompt you to reset these parameters.

How to keep your settings: To avoid having to reset the time and date, always keep the battery sufficiently charged. If you do not plan to use the device for a long time, charge the battery before storing it. If you need to remove the battery, try to minimize the downtime or connect the device to an external power source (via the charger) to maintain the internal settings.

Practical tip: Charge your battery regularly, even if the device has not been used. The battery of the Canon PowerShot SX70 HS discharges gradually over time. We recommend charging the battery on the day of use or the day before, and recharging it once a year if the device remains unused for several months.

Question 3

How to trigger a Canon EOS M100 without a mounted lens?

Accepted Answer

The Canon EOS M100 is designed to block the shutter release without a lens to protect the sensor and internal mechanisms. However, contrary to what the old answer suggests, Canon offers an official custom function to allow this practice if needed.

Activation via custom function C.Fn III-4: Access the Customization menu, then select [C.Fn III:Operation/Others]. Look for the custom function C.Fn III-4: Trigger shutter without lens. This function has two options: 0: Off (default setting, blocks shutter release) and 1: On (allows shutter release without a lens). Select 1: On to enable this feature.

Procedure to access the menu: Press the Menu button, go to the Customization tab (key icon), then navigate to [C.Fn III:Operation/Others]. Use the navigation buttons to select the custom function number (III-4), then change the setting with the W (previous) and X (next) buttons to switch to 1: On. Press M to confirm and exit.

Warnings and precautions: Once this function is activated, ensure that the camera is clean and that access to the sensor is safe before triggering without a lens. The 24.1 MP CMOS sensor remains exposed to dust and elements. This option is useful for digiscoping (astronomical observation with the camera), using specialized adapters, or testing, but disable it as soon as possible after use.

Deactivation: To restore the default protection, return to C.Fn III-4 and set the parameter to 0: Off. This will prevent any accidental shutter release without a lens.
