I'm getting really fricken sick of this. Every time, without failure, that I take a photo trip somewhere; every time that I get a chance to just be with myself and my camera and I can really create - I get film developing problems. Granted, in the past I have used expired film, etc, but this time I was armed to the teeth with fresh Tri-X and Plus-X film. Camera checked out days before with both film backs, no problems. None. So then I get back from a trip to Lake Superior, 19 rolls later, and i end up with uneven development issues, negatives dense like bulletproof kevlar vests... But this one wins the grand slam - some kind of line that has higher density than the surrounding areas that goes the entire length of the film, about 1/3" or so from the film edge. It's a tad irregular. It's on the last three rolls I have processed from a certain place where I had gone through and tested a different developer for the film, HC-110, before I processed the film. I exposed an entire roll and tested it, then I exposed one more and tested it too, just to be sure. Squeaky clean negatives. Then I develop the stuff from the trip exactly the same way - 8 minutes at 1+50 from syrup, agitate every 30 seconds for 5 seconds. 70*F water. The densities of the negs are great. Please look at the neg and see if you can identify what that line is. I am so effing sick of having these problems I'm thinking about just hanging up my hat and quitting this. I am so frustrated I am ready to take my equipment and just give it away and walk away. Fed up. I mix the chemicals with either distilled water or boiled tap water that's been cooled off, or a mixture thereof. Stop bath is fresh (indicator) and fix clears a film strip in 30 seconds. I have tried all kinds of chemistry, distilled or boiled water, different agitation. When I cured the uneven development problem, it's automatic that another one would show up. Like fucking clock work. I'm at my wits end. Don't know what to do.
