We had one client about 5 years ago that had us process several rolls of vintage film for them and have never paid us. We have tried on repeated occasions to get payment from them but have been unsuccessful. Just lately our company has been compiling sample photos of our processing of old film. This customer has some fantastic picture dating back into the 1940s that we would like to use as samples. Does anyone have any idea if at this point, we own the pictures or not. From an ethical stand point I feel that I should be able to use them because they asked us to do a service for them and they have never paid us for that service.
