The Xtol was fresh, mixed up in distilled water, but diluted with tap water; I generally get very good results from this combination. The film was bulk loaded and exposed in an M6 with a 50 Summicron. Film was pre-soaked and processed in a Jobo processor wth seven other rolls of film. The images seem ok - density is what I expected. BUT on the non-emulsion side of the film there is a green patina. Re-fixing does not get rid of it. One other roll of bulk Tri-X from the same batch shows some of the same patina on the sproket-holes of one edge of the film only. None of the other film was so affected (Delta 400). Now in addition to the patina (which in several spot looks like small circular blooms resembling mold growth), there is a"negative" images in the patina, including one rectangular one that has clearly defined edges which sits in the middle of the strip astride two images (like a "clear" rectangle, less than the width of the film) . If the patina were not on the non-emulsion side of the film, I would say that it looks like the film was fogged. But what would produce this sort of fog? Film was shot at home, never put through an airport x-ray machine (by me at least) and has sat undeveloped in my bag since late May (I'm just catching up on some developing . . .) Any ideas?
