Today I plan to buy my first large-format camera, A 4 X 5 Crown Graphic Graphlex. It seems like a deal for $200 with three lenses, three film backs and a book and accessories. I shoot 35mm and medium-format, so I'm acquainted with film. What confuses me is the loading/unloading process for large-format negatives. The seller tells me it needs to be loaded in a film bag or dark room, and that he had the shop unload the film. Is there a better way to do this, and do I send the negatives to a lab? If so, which lab do you use and what is the approximate cost? Thank you very much. Edwin.
