For my b+w large-format developing I use a Doran 4x5 tank, and am having problems with uneven development. As a firm believer in intermittent agitation who is satisfied with the results (in medium format) from my stainless steel rollfilm tanks, it has been tough for me to figure out how I should be agitating my 4x5 tank properly. The tank, when closed, leaks out of the top lid considerably (and has no sealable pouring hole) so inversion is definitely out. Following a minute of pre-soaking the negs, I agitate for a full minute then do a sort of gentle figure-eight pattern with the tank held vertically for my normal 10 seconds on-the-minute agitation technique. Unfortunately, I often end up with areas of lighter development along the vertical edge of the negatives in several instances (not all).(posted 8071 days ago)It would seem that this is caused by the developer flowing between the sheets of film in a pattern stemming from not agitating randomly enough, but I'd like opinions/suggestions on the matter. Thanks in advance for your help.
