Canon 30D - Manual (Page 15)

Flash Tip for the "*" Button:
Preflash - Eyes Closed No preflash - eyes open
The 30D, like most cameras, fires a preflash a fraction of a second before the
actual photo is taken to set how bright the flash should be. Then it takes the
picture a fraction of a second later with a second pop of the flash. Most of the
time the first pop of the flash starts people and pets blinking, which almost
guarantees that their eyes will be closed in the actual photo!
Use the * button to pop the preflash before you take a flash picture of people
or pets. Now, so long as the * stay lit in the finder, the 30D will only fire one
flash for each photo, which won't cause people to blink the moment before the
photo is taken. Be sure to press * again if you change your distance.
[+] - (+) Button: This is on the top right of the rear of the 30D.
In playback: Zooms in (+), or if you're in the 9-image display mode
(checkerboard), returns you to an individual image.
During shooting: [+] allows you to change the selected AF sensor or
sensors. I explained this above under the Unmarked Button above Big Dial.
