Hello, I am looking for a new point&shoot camera... Ultimately I want a camera that is compact, nothing too big.. something I can fit in my purse. I have been looking at 2 canon's which are the SD880 & SD990.. my only concern is the manual on the SD990, I haven't had much experience with using manual, I usually only set my cameras to Auto.. Do you need to use manual to take a good photo with the SD990? Any suggestions on which camera would be good? Thanks.
