just curious
Ok so I developed five rolls in my Jobo lastnight and all five of them appear to have this ugly brown "trench" -is the best way I can put it- right down the middle of the roll. There is the appearance of some kind of halo's around the sprocket holes on all of the films also.
I use 5L bottles for my solutions, and then I have 1L bottles which I use for day to day developing and I generally dont measure out exactly how much I put in the tank -safe to say that I always throw in about 700-750ml of solution into my tank (its a Jobo 2551 five reel tank), and I generally use that 1L solution twice and rarely three times before I take from my 5L stock bottle.
Ok so two things about lastnights dev session; Id used 650ml out of 1000ml the previous night on another dev excursion (basically if I use it twice then there is 350ml of unused solution which gets added to the just used solution and I see that as a kind of replenishment), lastnights dev I did for 7 minutes (the film was Tri-X, and it was 20c), and I for the first time actually measured out the developer solution according to the intstructions on the 2551 tank which says 640ml (so I was over my 10ml BFD..) -my thoughts are that this amount is in fact not enough...
The second thing is that this bag of XTol is in fact just and I mean two weeks, out of date. Remember that I developed five rolls the night previously with no issues. My friend believes that even though there is that 350ml cross-over of unused developer in the 1L bottle, the XTol's post-dated-ness', isnt enough to counter the possibility of its possible exhaustion.....
Opinions & possible repair possibilities Please.
Thank you.
