Trick Tip:
EXPOSURE

General: Tends towards overexposure as all Canon compacts. No big deal: set it to -2/3 compensation all the time and it's fine. If you don't do this you'll get a lot of bad images.

TRICK: Auto Exposure Lock (AEL): Press and hold the shutter halfway. Tap the ISO button and the SD550 measures and locks the exposure. AEL shows on the right of the screen. Recompose and shoot. This exposure value stays locked for more shots until you press the ISO button again.

TRICK: Flash Exposure Lock: It really works! Press and hold the shutter halfway. Tap the ISO button and you get a preflash which sets the flash exposure. FEL shows on the right of the screen. Recompose and shoot. This exposure value stays locked for more shots until you press the ISO button again.
