After years of research (and several not-so-successful attempts) we've got the answer for large large format processing: the SP-8×10! In fact, we’re so impressed with the concept that we’ve filed a patent.
Simplicity: No frames/holders to fumble with in the dark. Just take the lid off and drop in your film. No seals, O rings or complicated mechanical contraptions. And it requires only 500 ml of chemistry.
Flexibility: It will handle anything smaller than 8×10. Simple dividers keep smaller sheets separate. The production version will handle anything between 4×5 and 8×10: 5×7, 4×10, 4×5. Yeah, 9×12 will work too. You should be able to adapt it for those odd-ball sizes that no one else has heard off.
Proven: tray processing has been around since, well, the first days of photography. It just works.
