What is going on here? The dust and scratches I understand but the streaks I do not. I have had the issue with 35mm Tri-X and now that I have moved to shooting it in 120 the same thing is happening. But it cannot be just the film or the back that I used for Tri-Xm because I see the same streaks with FP4+ but to a far less extent. I used Rodinal 1:50 at 68F with 30 sec agitation and 10 sec every minute after that. The only thing that I can think of is that I used tap water instead of distilled water for the developer. Is this what the issue appears to be or is it something else?
