I need a daylight tank for 5x7 film processing. I would do the trays but don't have access to a darkroom. I have been doing some research online and found some posts that suggest it is possible to process 5x7 film using a Jobo 2830 meant for prints. Is this correct and if so then what kind of mod do I need to do to make it work? Alternatively if I am willing to process one sheet at a time then can I just use a Paterson tank meant for roll film, just slide one sheet in there with the emulsion side in? If I develop by rolling it instead of inverting it then it would avoid the scratches, right?
