In this new era, the camera on a smart phone can be far superior to the point and shoots of yesteryear. But, this is not the case for all of them. A bad camera mixed with poor shooting practices will destroy an image.
First thing is first. How do you take a picture with a camera phone. It is different than using a DSLR. The first thing to keep in mind is the extreme lack of power. At most you will have 8mega pixels. Of course there is no optical zoom either. No changing of aperture, no adjusting of exposure times. You are alone.
