Well this morning I was continuing my adventure with Mr. Gainers develoers. Needed to redo some test shots. Decided that I was doing these out the window from the house because the weather is impossible.(colder than..) Brought all the stuff up stairs and proceded to test Tri-x,HP-5 and J+C100. Didn't really wait too long for the film to defrost. After initial development of the three films the only one that did not have dichroic fog was the Tri-x. The other two crapped out on me. I guess the one to use in extreme conditions is the Tri-x. Curious if anyone else has had any experience with this??
