Just to give you an idea, here's a picture I took at a larger resolution with a 5.0 MP camera and edited with GIMP (which is sort of like a freeware version of Photoshop). The original resolution was 1600 x 1200, and I cropped and scaled it so it's now smaller. Some other things you might want to adjust with an editor are levels, brightness, contrast, color balance, and saturation.
