If you have a scanner that uses a fluorescent tube, rather than LEDs to illuminate the object, then you should aim to scan as much as possible with the middle of the fluorescent tube. The reason for this is that the tube's characteristics change most nearest the ends of the tube, especially if it has been used a lot. So, with a fluorescent scanner, put the photo in the centre of the platen with the photo's long axis running down the platen. In that way you use the smallest width of fluorescent tube, and the bit you use is the middle bit.
Scanning a full-size piece of really white paper will often show up the way in which fluorescent tube characteristics affect a scan. -- Regards, Ray Forma Tel & Fax 61 (0)8 9335 6568 Mob 0428 596938 No Microsoft software was used in generating or sending you this email.
