QUESTION

I am scanning 45 yr old slides. They look good for the most point when using the projector but when scanned into the computor they pick up a lot of blue hue.  I can get some of it out but they still don't look like the original.  I am using the vupoint scanner.  So is this a scanner problem or a computor problem.

ANSWER

My guess is that this is a scanner problem or a scanner settings (software problem).  Did you set anything in the software to tell it that these are old photos?  The color yellow is usually the first color to leave a slide which leaves a bluer hue.  At anyrate, I think that the full-blown version of Photoshop would correct this deficiency, making them pleasing again even if not exactly like the originals.

Fixer spots and stains look like bleach marks on a print or negative. If discovered on a relatively new photograph, then rewashing will probably stop it from slowly spreading across the photo. If the stain is already spreading like leprosy across a print, it has probably also traveled the full thickness of the print, and some combination of washing and cutting may be necessary. If there is no spot on the print, but the entire image is slowly acquiring a bleached look, then the paper is contaminated with residual fixer from incomplete washing when it was originally processed. If the print can hold up to it, additional washing after the fact can stop the progress of this bleaching.
