Cinestill DF96 monobath

Huss, which art museum were you visiting?
Great photo of the kelp on the beach. It happens often along the northern coasts, especially when the big breakers come rolling in.

It was The Getty Center in Brentwood (Los Angeles). A lot of stuff has been washed onshore with these storms!
 
My freshly opened bottle of DF96 - with intact seal - has given me bromide streaks on the first two rolls of Kentmere. This is extremely surprising and disappointing, as i the past I have only seen that when the solution is near expired.
My technique is unchanged, so the only thing I can think of is this is a bad batch of DF96.

Posting for transparency in this process.
 

That is disappointing. Have you contacted them?
 
Maybe its time to mix your own...

Monobath Developers

I've been playing with Don Qualls' monobath and found good results on 4x5 film in a tray. Today I tried it on a roll of 35mm Plus-X. The negatives look lovely, except for marked drag marks at the sprocket holes. I had read the instructions for the New55 commercial version of this recipe, which...

No, they’ve been good to me in the past having exchanged other bottles which were delivered w leaky seals etc.
I’m mentioning it here though so people see the full experience, not a one sided everything is awesome angle. I don’t find that helpful in case others are looking for info.

I’ll make lemonade out of these lemons and switch over to shooting 120 film which I havent done in a while. Never had bromide drag issues there as there are no sprocket holes!

Ari Jaaksi (YouTube channel Shoot On Film) has noted and demonstrated with images that bromide drag does still occur with 120, it just looks different. There will be dark (in the positive) drags below bright (in the positive) areas, where more developing action has increased bromide content of the developer (and hence density of the solution) locally. That said, I had to look quite closely on his examples to see it (even with an HD monitor viewing the video in full screen, giving image size comparable to what I see here for the largest inline posts). The point of his video was that he matches film orientation in camera, film orientation in the developing tank, and subject matter to make the bromide drag from stand development part of his composition.
 
Same bottle that had bromide drag on the first two rolls. This time I developed at 75 with the required additional agitation. Still, before it always was fine at 70..

Tmax 400

Hey, what time/temp are you using for Acros in DF96?

Lacking any data, I'd surely try a short clip test at the default 75F/6 min (for tabular grain) constant agitation. If underdeveloped, increase temperature 2 degrees or reduce agitation to 5 inversions every 30 seconds; if over, reduce temperature 2 degrees -- and then retest.
 

Yup, that would work too, but being lazy, I'm hoping Huss has an easy answer.

Double the time for Acros II to make sure the base clears. Same for all those those tabular grain films like Tmax or Delta.

Thanks! Kind of what I expected. So far I've only developed Tmax 100 with DF96, so I can treat this exactly the same.
