Mottling and Streaking

hell...I can't see it ....
post it with arrows maybe...

but it you use tubes...sure as shitiuh...you got anti-halation dye problems on the back...it LOOKS like emulsion, but it ain't...done it...been there

I use the JOBO CPP2 processor with the large film drum.

I agree to use a longer development time, with the appropriately more dilute developer. I experienced streaking when reducing my development times to control contrast, using BTZS tubes. I was developing between 4 and 5 minutes with D-76 1:1. I have changed to D-76 1:3 and processing around 11 minutes with Tri-X at 70 deg F. No streaks so far using the longer process time and more dilute developer.

increasing the time sometimes helps, but not always--it's a crapshoot depending on the fickle forces in the tube..if you go back and look on the film very closely, you'll see the streaking--but light streaking doesn't affect anything if you're printing--I do reversals--so you SEE this stuff on a light table if it's there--therefore it's completely unacceptable.

what will give MORE reliable success than increasing the time is MORE solution--it provides more presssure to get the liquid in back quickly and more evenly---however even this can't prevent it from happening in my experience--not if the back of the film is pressed against the tube--there will always be uneven wetting back there most of the time.

Thanks, everyone!!!
