I tested 2 sheets of Pancro 400 .
I've been using an old but well-frozen box of Ansco 2831 to test some reconditioned 4x5 cameras, holders, and Grafmatics for proper functioning and light-tightness.
I can't find any information about this film nor developing it, not on line nor even in old Morgan and Morgan data that I've retained. At the moment, I'm trying a rating of ISO 50 because of the film's age and developing it in XTOL 1:2 as a compensating stand-developer for 14 minutes, but I really have no idea.
Does anyone have any data or suggestions?
developing time was 17 minutes in D-23 at 20º C
I didn't know Bergger still sold that. Cool. I've never tried it.
I think there was an old version of Pancro and a new one, but don't quote me on that. This version is available from 35mm to ULF I believe on special order. What a crazy film. It's wildly grainy in 35mm. The grain is of course reduced when you go up in formats so on 4x5-8x10 it's a fantastic affordable emulsion. It has a very long tonal range, especially when you use their very weird Superfine developer. I generally run it in D76 because Superfine loses you 1 stop. The 120 version was coated by Ilford I believe and pretty much every roll I've run has had emulsion mottling from the backing paper. I am hoping a new batch is in circulation that fixes this issue because it's great in 120!
I shoot it in 35mm all the time despite the grain. Some of my favorite P&S images have been on this film. It looks like Super-XX a bit, but it's cheaper and easier to get.
My circa early 1970's GAF catalog shows Type 2831 is Versapan and had a "Film Speed" (their term) of 125. No information on developing or developers. I used this film 50 years ago (egad, 1971 was 50 years ago).. Looking at my 50 year old notes it looks like I used an Ei of 100 and normal developing time was 17 minutes in D-23 at 20º C which, quite frankly, seems awfully long now! Take it for what it's worth. Not sure if I was using film hangers and tanks back then. Today, and for many years past, I've developed sheet film in a tray.
In one of his books Minor White enthused that Versapan was particularly flexible for expansions and contractions by varying the developing times but I don't see any specific times that he was suggesting.

Some of you readers may remember that I tried some 1960s 4×5" Versapan film packs about a year ago. The results were amazingly good for 50 year old film. I exposed at EI=64. Northeast Photographic developed it for me. Support one of our advertisers.Thank you for the information identifying 2831 as Versapan. I erred in my recollection and thought that Versapan was a generic trade name for a variety of GAF files, of which 2831
It's in his Zone System Manual, New Revised Edition, copyright 1968, that White notes that Ansco "Verapan" (sic) can be expanded as much as N+5 and contracted as much as N-4 with "some developers." He gives no further details. That's probably what led me to try this film in the early 70's. My GAF catalogue which I cited above includes this about Versapan: "...and can be developed to a wide range of contrast."
1975 sounds about right for the demise of Versapan. Looking through my archive of photographic buying guides and photographic supply house catalogues I found Versapan still showing in 1974; 1978, the next year I have, GAF photographic films are not listed.
You are very fortunate to have had a class with Minor White. I always wanted to do one of his workshops but never got to it.

Isn't that just the same?My most recent large format sheet film purchased from: www.freestylephoto.biz
4x5 inch Foma Fomapan ISO 10O (50 sheets per box)
4x5 inch Arista EDU Ultra ISO 100 (50 sheets per box)
Isn't that just the same?
That way, I can process one sheet of each, evaluate, and process the second sheet accordingly.
