To adjust the ISO settings, press the ISO button located on the top of the camera. Use the Main Dial to select the desired ISO value. The selected ISO will be displayed on the top LCD panel.
First, ensure that the battery is fully charged and properly inserted. Check the battery compartment and contacts for any debris. If the issue persists, try a different battery. If none of these steps work, consider contacting Canon support.
To perform a factory reset, go to the Menu, select the 'Clear settings' option, and then choose 'Clear all camera settings'. Confirm the reset when prompted.
Ensure the camera is off and remove the lens. Use a blower to gently remove dust from the sensor. If needed, use a sensor cleaning swab with an appropriate cleaner. Avoid touching the sensor with your fingers.
Download the latest firmware from Canon's official website. Copy it to a formatted CF card. Insert the card into the camera, go to the Menu, and select 'Firmware update'. Follow the on-screen instructions to complete the update.
Ensure the lens is set to autofocus mode. Clean the lens and camera contact points. If the issue persists, try resetting the camera settings or consult the manual for additional troubleshooting steps.
Press the Menu button and navigate to the 'Quality' setting. Use the Main Dial to select JPEG format. Confirm the selection to change the file format.
Store the camera in a dry, cool place. Use a camera bag for protection. Remove the battery if the camera will not be used for an extended period. Consider using silica gel packs to control humidity.
Take a photo of a white or grey object in the same lighting conditions. Press the Menu button, navigate to 'Custom WB', and select the image taken. Set the camera to use Custom White Balance in the White Balance menu.
Ensure the exposure compensation is set correctly. Check the ISO, shutter speed, and aperture settings. Review the metering mode and adjust as necessary. Make sure the lens cap is removed.
