It seems that I am having more than my fair share of development problems of late. Here is another one. I have seen these marks before in the past, but thought they were banished after my recent trip to Cornwall where most of my negs were in good shape. What I am doing is not rocket science and my methodology was and does work fine for the most part. However, this stuff always happens on the really important negs! Here is an example of what I am experiencing. I get blotchy rebates, and banding, sometimes both. I have changed the light traps in ALL my film backs to factory hasselblad traps. Film is either Neopan-400 or TMY-II. It does not seem to matter. I am using Pyrocat 1:1:100 using semi stand, or as Sandy King says, Extreme Minimal Agitation. It has also happened when I develop ACROS in Rodinal 1:50 with agitation every minute. I've scrubbed my reels more times than I'd care to imagine with boiling hot water and strong bleach with a toothbrush, and or scotchbrite pads.. I've tried either presoak, and not presoaking. I've tried inversion figure of 8 agitation, and combination rolling the tank to minimize air bubbles. It happens in both Steel Hewes reels, or Patterson plastic reels and tanks. nothing appears to get rid of this issue. I do not use photo flo in the tanks. I manually dip the film AFTER the wash and hold both ends of film to form a loop, and run the loop through a bowl of distilled water/photo-flo and am diligent no cross contamination occurs. Photoflo never gets on my reels or in my tanks. I used fresh chemistry, and did not squeegee my film. What am I doing wrong?? I am at my wits end with this crap anymore. :-( Other folks can be far less diligent in their processing and not have these problems at all. It's just beyond me as to what to try next? I forgot to add that the neg scans I uploaded into the gallery... ALL of them had to be cropped ot get these issues out of the frame area. As you can imagine I am frustrated as hell.
