I have agreed to assist a local historical society in archiving their vast collection of photographs. I will be scanning the prints, retouching them, and adding keywords for searchability in the future.
My question pertains to the copyrights of these photographs. Part of what they want me to do is establish an online service which would facilitate the ordering of prints from the scans that I am making.
The society is always being contacted by individuals looking for copies of photographs of their relatives, or locations in the area...etc. My vision is an online utility that allows individuals to search through the image archives and order prints from the photographs.
What copyright issues am I going to run into? 95% of these images were personal "snapshots" donated to the society by members of the community. The remaining 5% are either from unknown origins or were donated by businesses in the area. Nearly all of them have a snapshot quality that make it obvious they were not professionally created. However, there are a few that were clearly posed, formal, family portraits that were commissioned at some point in history.
Help? Thoughts? Advice?
