    PKM speaks the truth once again. I rarely use my jobo for color, would rather send it to crc or duggal. makes life easy for b/w though.

    And I wouldn't want to use it for B&W since I choose a film and agitation scheme that I like for the results I want that can't be duplicated by a rotary tank.. We are all so different

    Adding to what Chris was saying about using constant agitation for color:
    I wouldn't expect it to mess up color, either. C-41 developing is 3:15 with agitation every thirty seconds, so that's close enough to constant as it is!
    I've done all my C-41 so far in tanks, and the changes I've made to my developing that yielded the best results were 1. using a developer starter (applicable only if you're not using a kit), and 2. at PE's recommendation, adding an acid stop after development.

    I would not be shooting 4x5 black and white if I did not run the film in my CPP2, too inconsistent otherwise. With the exception of using a slosher tray ( I also have one ) , you look at how master printers like John Sexton come to rely on rotary consistency and realize just how much that frees up your eye in terms of creative exposure evaluation.

    Indeed, we are all different, I find the time, money, gas and film price when shooting 4x5 too expensive to mess around with so I opt for high consistency...that and I probably don't have the same level of patience in trying other sheet film souping methods compared to roll film in tanks which I love.

    What a great conversation. I've been sitting on the fence about trying B&W roller development with one of those little Unirollers like Stone has and then C-41 with a phototherm unit. You guys have convinced me to do it. Thank you all.

    It's very true, though kodak nowa days has its own proprietary QA system and materials.... The standard parameters have all been established in a Jobo machine at one point or another in history.

    Go for it. I started doing it for sheet film but I like the process so much I am moving my roll film development over as well.

    Can someone explain JOBO Processors to me?

    Maybe I'll do this with my 5 roll tank? Because I only need enough chemistry to cover to the center of the tank correct?

    the best way to find out exactly how much liquid you need is to take a bum roll of crap film you'll never use (way expired drugstore c-41 is perfect), spool it onto a reel, put it in the tank on the spindle, but don't push it down to the bottom, let it sit in the "top roll" position...as if it were the fifth of 5 reels and put the tank on its side. Add something like 400-500ml of water and hold the tank (with the lid on) parallel to the floor and rotate it (or put it on the roller) if you pull out the film and the whole roll is wet, it's enough. Add on 50ml just to cover your bottom, and there's your figure.

    For what it's worth, my jobo drum uses 270ml of chemicals for the 2x 35mm rolls drum. I would extrapolate that for a paterson 5 reeler (I've got one too), you'll probably need about 550ml.
