I've been developing sheet films for some time . I have used Tmax 400, Tri-x, FP4 etc. for years. Lately I decided to try Tmax 100. The films have a distinct green cast when developed. I have not seen this problem with roll film or any other sheet film I use. I use the same chemistry - pre wet, Xtol, Kodak Indicator Stop Bath, Ilford Universal Fixer, rinse, Kodak Hypo Clearing Agent, wash & Photo Flo. Has anyone else seen this? Is it a problem?

I see this fairly often after I put the negatives in a sleeve and then place them against a white background such as the back of a contact sheet. I don't think it's a problem. I posed a similar question to the large format newsgroup a while back. Someone explained what it was but unfortunately I've forgotten. He assured me that it wasn't a problem so I've pretty much ignored it since. I get a similar "tint" with Ilford HP5+ sometimes also.

Bill, I've processed Tmax 100 several times and the negatives always looked normal. The only thing I do different is a water rinse instead of stop bath.

Bill, Try a 2 - 5 minute pre-soak in LFN, or Zonal Pro Archival Rinse, not Kodak Photo-Flo, then develop, water rinse, fix for double your current time, wash and end with another one minute in a fresh batch of the same wetting agent you used for the pre-soak. Contained in this are three things each of which will help solve the problem and combined you should never see the remains of the anti-halation layer again. Jim
