Depends on what he's doing with them. Why are you scanning at 600dpi anyway? And at what dimensions are you scanning? If ALL you are doing is scanning in 5x7/3x5's or whatever and not doing ANY resizing, just printing at the scanned size then Mr. Wiser is totally correct. You're scanning in way too much information. Drop it by half and you'll always have the option of doubling your print size for a future application. 600dpi is often my BARE minimum, as I like to enlarge quite a bit.. While scanning photographs is not the highest quality process I prefer to factor in some extra pixels for later discretion. More details? And what OS are you using? I know we're in X-Newbies here, just asking to help you with helpful answers.
