Gary: Thank you very much for the info. we would love to be able to do all that you mentioned, but this is a small museum and the finances are not available for all of that, at this time. We just try to do the best we possibly can w/ what we have and can afford. That is why we are simply trying to find out about the heat and light.... in order to determine if scanning is even a viable means of reproducing the photo for records purposes or not. If you think of anything else we should be aware of... please feel free to contact us again! And, again... Thank you! Ginger M. Young
