Hello everyone, my first post here. I have been developing 35 mm film for a while. Recently, I had a fixer go bad (foggy negative) so I mixed a new batch from the same concentrate. Today, I also mixed a new batch of dev powder (Xtol, standard concentration) and developed an Ilford HP5+ 400. No push/pull. The whole negative turned very clear, and I can barely see anything (see "film" attachment). Therefore, I figured the developer must have been bad. So I tested it with a small piece of film and it turns dark grey in 1 min, so it seems to be fine (see "test" attachment). I also tested the fixer and it works fine (otherwise the negative would be cloudy too). I don't know where the problem is. The film was not underexposed (not the WHOLE thing anyway). Any tips or advices are welcome.
