Hello, I'm a relative beginner with photography which will soon be evident from my question. I own a Sony DSC F828 which I understand is a good camera to learn with. My question is related to image size. If I am to print photos in smaller sizes f.e. 8*10" or less then is it sufficient if I take the photo in 5MP or will I get still better resolution in the printed image with 8MP? Thanks in advance.
