Yet another Diafine thread...

[Roman]

The post man just rang and brought my Diafine that I got from Foto Riegler here in Austria. I ordered the quart package (gallon is not available here). Along with the developer came a German instruction sheet - and the data on that one is not identical with that on the package for a few films; also, some films I use are not mentioned at all, so I'd appreciate if someone has expereinces with those:

Neopan 1600: Package says EI 1200, sheet says EI 2400 (sounds unrealistic).
TMax P3200 - EI 1250 - any experiences?
TriX Professional 320 - any experiences with the old one (I still got about 50 MF-rolls of that) at the recommended EI 1000?
Has anybody tried Efke 100 in Diafine?
How about Fomapan 100?

Thanks,

Roman

I just developed a roll of tmax p3200 shot as 1200 in diafine. The negatives looked thin but scanned very well. So I think this combo works. I took some shots rated at 800 on the same roll (this is diafine, after all) and though the negs looked good to my eye they were hard to scan.
Haven't tried tri-x 320 in it yet.
You didn't ask but panf+ at 50 is just about perfect.

Has anybody tried Efke 100 in Diafine?

Roman

I bought a big batch of Efke 50 and 100 and did it all in homebrewed diafine. It came out very nicely indeed at about 100 and 200 respectively. Mine was homemade, but I was following tips from a real diafine users reporting similar results. I think the old style silver-rich emulsion must suit diafine; very nice.

Acros 100 is also very nice, but slower than Efke 50 for me; best at about 80.

Good luck...

Roman,

A long ago I settled on Tri-X and Plus-X along with the Ilford HP/FP series as "best" for me in Diafine, so I have not experimented with different films for a very LONG time. We won't go into the exact number of years here.

Anyway, just based on my experiences, I would say your data sheet is incorrect with the rating it gave Neopan.

One test roll should answer all questions. With 'high speed' films I would start with a series at -3, -2, -1, rated speed, +1, +2, +3 and see what you get. By the way, you might get a bit of surprise information regarding your camera's shutter speed accuracy while you are at it.

The thing about Diafine is that it takes the development cycle out of the picture, exposure wise. You can't blame errors on over or under developing with a compensating developer like Diafine.
