I tend to agree with Pesto. I would just reprint. I have a film photo that I've had on my desk at work for 9 years in a UV frame with the sun shining on it all year long. It is slightly faded when I compare it to the 4x6 verison in a photo album. But I just reprinted it from my negative with no problems. I thought it was funny that it cost less to reprint a 8x12 now than it did 9 years ago.

Jennia: Thank you for taking the time to summarize the data.
