I'm not real smart, but I'm slow to make up for it. Bought Nikon Coolpix P90. Took some wildlife shots... wasn't getting good focus with zoom so took some without zoom. With the resolution of the camera, I can zoom the existing pics up using the camera features and center them and they are acceptable "keeper" shots, but I don't know how to save them in the edited version. Any one help me resolve this neophyte problem?
