I had assumed the more pixels, the better. But I think I read somewhere (before I bought my camera) that below certain print dimensions, extra pixels just increase file size, without any appreciable difference in the result. I will be printing 8.5 x 11 inches with an HP Photosmart printer. Do I need to use all 6 million pixels on my D100? Or can I shoot at the smaller resolution? Also, how badly does the greater JPEG compression offered by the "Normal" and "Basic" modes degrade the image, again considering my intended print size?
