I never laminate or treat old photographs in any way other than storing
them in a cool, dark place. This, after scanning them in color (even black
and white ones). I can now *improve* my photograph, enhancing colors and
contrast, remove scratches and blemishes and, usually, my copy is better
than the original. I can display my pictures anyway I please, confident in
the knowledge that if one fades, I can print off another one. I can also
distribute copies to interested family members who are usually willing to
let me borrow their precious photographs for copying.
