Please note that these suggestions are a guide. Many custom function settings will be to the photographer's individual preferences, but leaving these few set as below will assure that anyone who picks up the camera will start off right. That's important for shared equipment.
| Sensor dust |
Turn the camera off when changing lenses. If the sensor is charged, it will pick up more dust. Also, clean the back of your lenses before mounting. To clean your sensor, use the "sensor cleaning" option in the menu to lock up the mirror with an un-charged sensor. Then use a blower bulb to gently clean. NEVER use dust-off. |
| White balance |
For the most accurate balance, use custom WB by shooting a white card, selecting that image in the "custom WB" menu option, and then setting your white balance to "custom." Your white card setting will ONLY be used when you shoot on the "custom" setting. |
| New in the 20D |
The on/off switch has a third position to take the place of the command dial on/off switch. If you put the main on/off switch in the top position, it locks the command dial. |
