I feel strange having to ask this because it is the first roll of film I have ever had that did not turn out okay. So, I just developed a roll of Tri-x, 35mm, which is my primary film. When I pulled it off the reel it had numerous milky white patches running across the length of the film. They were not clear like unexposed film, nor were they black like a light leak. This leads me to think it was a problem with either the film or the chemicals. I'm leaning toward the film because I developed a roll of HP5+ just prior to this and it is fine. The only difference between the two rolls was that I mixed fresh developer for the second roll (tri-x), as I use DDX one shot. Still, the concentrate was from the same bottle and the distilled water was also from the same bottle. All procedures were the same as I have been using for a long time. Oh, I also poured the stop and fixer back into their respective storage bottles after the first roll to insure that the chemicals used for the second roll were "replenished." Also, the negatives look normal otherwise, i.e. the film was exposed and shows all the normal photographic detail, just with milky patches over the film. Any thoughts?
