Does anyone have 4x5 and 5x7 sheet film of ANY KIND, exposed or unexposed, processed or unprocessed and willing to send me a few for postage? I need one of each to use in an experiment. Initially, I am only going use one for size template, so all I need is something perhaps from floor of someone's darkroom. The only limitation is, the film can not be physically damaged, as in torn or bent. Having a giant hole in the middle is actually ok If anyone can help me out, I'd be greatful. I'm in USA and 32703 zip code.
