Oh.....I always wondered about those preset things. Never understood why someone would buy a nice DSLR and then let the camera make all the decisions.
That being said, it was a little frustrating the first few weeks when my wife would put it on P and take better pictures than I would using my new found "knowledge" But after a little while things started making sense and Now I am almost never satisfied with the P mode shots. For me it's either shutter priority or aperture depending on what I am trying to do and then manual if I am doing pano's or sequence shots.
Anyways, good luck with your search.
