Right side:
Light Bulb: Press this to light the LCD display.
AF - WB: Tap this, and now the two control dials can change these. It will stop
accepting input 6 seconds after you're done twiddling, or the instant you tap
the shutter button.
AF mode is shown on the right of the LCD, it shows AI FOCUS. WB is shown
on the left of the LCD, it shows AWB.
Important: these, as all the buttons, only work if you've first woken up the
30D by tapping the shutter button! Once the 30D is awake and you've tapped
the AF-WB button:
1. Tap the AF-WB button and now the front dial, seen at the top of this
picture, selects the Autofocus modes. I explained these on the first
page.
2. Tap the AF-WB button and now the big dial on the back of the camera
selects among the various White Balance options. See my White
Balance Examples page and my White Balance page for the specifics.
3. Press the shutter to get back to shooting. You can leave the 30D alone,
or press the AF-WB button again to get it out of the adjustment mode.
