    Re: Problems processing 4x5 film, uneven negs

    Uniroller 352 (auto reversing) base and unicolor 8x10 paper drum plugged into a Gra-Lab timer. load it in the dark, process with lights on. Four sheets (4x5) at a time. 300 ml. of dev.
    Available on the auction site for cheap. My whole set up under $50.
    Do a search here and on $-bay.
    Not as cheap as trays but for me... easier and no problems.

    Re: Problems processing 4x5 film, uneven negs

    Welp I dove into the deep end and tried out tray processing for the first time. I did 3 at a time at first and they came out great! Very even negs, after that I had enough confidence to do 6 at a time and all of them came out very good.

    I did 1:1 D76 for 10.5 minutes, very weak Stop bath for 30 seconds, and 5 minute fix, pre and post wash for 2-5 minutes. My agitation cycle was 10s for 3 sheets and 5s for 6 sheets as Ansel and others suggested. Very good tonality and sharpness. I figured I'd mess it up but somehow they all came out the way I wanted. Thanks all for the helpful advice! I'll be posting some more of my work to Image section soon.

    To add to d.s. regarding unicolor or any other drum processor, fill the drum with reels or sheet full of water at the correct developing temperature for 3 or 4 minutes, drain if completely and then add developer. This will temperature control everything in there you don't do that, the temp will go up or down resulting in improper developing.
