    I find that I usually need to increase my development time when using a jobo processor, contrary to what everyone suggests. I'm not sure why this is; it may be due to developer exhaustion, even though the same 200ml of developer I'd use for tray developing 8x10 xrays results in a much weaker negative when I use that volume in the jobo processor. Haven't really figured out what's going on here.
    Perhaps increased aeration...

    I figured that as well; rapid oxidation. The other possibility is less exposure of the film to the developer as most of the time, the film is not in contact with the layer of developer at the bottom of the drum.

    200 ml is really minimal for 810. I am a believer in a little too much is better than a little shy. That assures that regardless of subject matter I do not exhaust the developer.

    This one was taken using a Hunter Penrose camera using a Ross 3A portrait lens 16 inch. Neg was 16.5 x 13.5 inches. Developed in 275ml of solution which required 20ml of RO9 developer. Too big to scan, copy taken with a tablet, isn't she stunning! Best model I could find with my reputation

    Correction, that should be 2750mil of water to 20ml Ro9

    Here is a recent image shot on the Carestream single sided stuff. I had my meter set at ISO 25 ( for my Efke 25). I developed it in Rodinal 1:100 for 11 minutes. I develop all of my 8x10 in one gallon tanks. The print is a carbon print and the cell phone shot is of the wet print.

    here's something else I'm trying, the biggest probs with mottling and streaking seems to be the film sitting on the bottom of the tray, I cut off the hanger on one of my old stand drop holders. It now keeps the reverse side off the bottom of the tray avoiding scratches and spent developer remaining stationary under the film. A lot easier to flip in the tray and move into the other soups.
