Pushing Arista 100 using Cinestill DF96 Monobath

Huss · Oct 4, 2020

So in a big pile of film that was sent to me sat a couple of boxes of Arista. Most of the Arista was 400 film, which is what I used to buy. But one was a roll of Arista 100 (expired in 2010). I did not notice that and shot it at 400. Luckily when I unloaded the camera I realized my mistake and figured this would be a good time to test the push processing ability of DF96.

Leica M3, Summicron 40, developed 4 mins @ 95 degrees, 30 second agitation to start, then 10 secs every minute.

Interestingly the grain was finer than Arista 400 shot at 400. And the tones look better.

If this is the relabeled Fomapan, you've rediscovered something I found back around 2007 -- that Fomapan 100 is as good a 400 speed film as Fomapan 400.

This is about a 50% crop from 35mm .EDU Ultra (Fomapan) 100 pushed to 400 in Parodinal.

Grain is almost indistinguishable from .EDU Ultra 400 in the same soup, developing time for the push is the same as the 400 at box speed, and shadow detail is very similar.

The film was dated 2010, so whoever provided Arista with the emulsion back then. I know that Arista Premium 400 was Tri-X, now it is Arista Ultra EDU and Fomopan 400 (which should be rated 200 or pushed 1 stop).

This was all an accident for me, I thought I had loaded a 400 speed film as that was all I shot from Arista in 35mm. But a happy one now! And I'm impressed with how DF96 handled the push +2.

There was Arista .EDU, which was Fortepan, and then there was .EDU Ultra, which was (and is) Fomapan. I've use the Forte version only in 4x5, but it seems rather similar to the Fomapan (at least the 400, which is what I have).

And Df96 handles modest pushes very well, as long as the emulsion doesn't melt (from the higher temperature) or you don't get bromide drag marks (from reduced agitation -- seems mainly a problem past about half the solution life).

Temp used was 95 degrees, and that was the 12 roll in the batch. I've found to avoid bromide drag with DF96 to use the 10sec/on the minute, and 1 turn on the 30 sec agitation routine. This is using the 75 degree basis.

How did you arrive to 95F? Seems pretty warm.
I have some DF96 coming next week, and a bunch of Foma Classic 100 around here so would be interested in giving it a try too.

Just followed the instructions provided w the DF96!
