This camera shoots at 5.1 mp and will do most of that computer stuff right in the viewfinder of the camera .. This camera is a EVF, electronic view finder, and very few point shoot cameras have this. It will enlarge, move, crop, rotate, change the megapixel count right in the viewfinder. Won't change color but it does have a manual setting that I use all the time after I autofocus on a subject and want to shoot at that distance. Keeps the camera from focusing every time you want to compose. Its much faster also. I do send emails at the 1280X960 with no problem. The 640X480 setting is only one third of one megapixel and some of them are amazing. IMO.. THanks.
