    Cool processing tank for 4 x 5

    This looks pretty cool, doesn't it?

    It does. And I like that you don't have to pick up the tank every time for agitation, making the process that much more repeatable. I also like that you can now use little solution without the need for continuous agitation, like you would have with a jobo tank with that amount of solution. It might make a great tank for stand development.
    What I didn't particularly like is the film holder, are you still able to wash off all the anti-halation layer on the back of the film? And can you wash the film thoroughly in this, like you can in a Jobo tank with the lid off?
    Also, it is still a messy solution. Even without a dripping tank to invert, you will probably still spill some with the plunger. Not to mention what would happen if you tip it over by accident during development.

    A shallow tray with locking grooves in the bottom to hold the tank should be sufficient to stabilize the unit and any spills will collect in the tray.

    That's very true. And I hope it all works out well. I'm in the seeing is believing camp when it comes to processing solutions. If this works as well as intended I'm definetely interested for the times I want to process only 1 or 2 sheets.
    I've just never used a solution tha is drip free. A 30c water bottle closes perfectly, but somehow there is no processing tank you can keep dry hands with.

    Looks like they are going to an inversion design (video for update #7)
    "...too sensitive to operator technique ...inconsistent results mainly with b&w films ..."
