I am trying to locate a film processing firm that will process 4x5" C-41 color negative films. I live in Salisbury, Maryland on the eastern shore. The closest large cities are Dover and Wilmington Delaware, Annapolis and Baltimore Maryland and Washington D.C. Next closest is New York City. It has been 16 years since I've exposed a large format color negative. At that time and those previous, I just drove to the film processor and handed the customer service representative my holders, they would have the empty holders ready for me when I got back from having breakfast. Alas, I no longer have the luxury of having a professional film processor near by. MY 1st QUESTION: Can someone please tell me of a large format C-41 processor closest to where I live. MY 2nd Question: How do you folks send your film off for processing? Do you send it in the film holders / double dark slides? Do you send it in the film boxes that the film was purchased in? I really don't fancy the idea of sending my film holders to the processor. And I don't have any spare film boxes that are empty to send the exposed film in. Is there another way of packaging the exposed film to send to the processor? Happy holidays to all, with thanks, Sam H.
