I've been in the LF world since 1964 but have always shot standard size film. I've either processed in deep tanks with hangers or in a merz or colenta rotary tube machine. I still have the tanks and hangers but sold or trashed the rotary machines a few years ago. Now I'm thinking of a 4x10 camera or back for my 8x10 and don't know what options are out there for processing this format. How do you process your B&W? I'm guessing most will say tray so how do you prevent scratching? Any way to run it in a Jobo? Thanks!
