i have a color digital photo that i plan on saving to disk and taking to professional lab for printing. the image is 300ppi. My question is, what image size is needed (width/height) in order to print high-quality at 8x10 or 11x14? the photo is being sold and must be of highest quality. It was taken with "JPEG large" quality with a nikon D200, which is about 3000x2000, or something like that. will this do???
