You can reply off list if you prefer I am using a jobo ATL 3 processor, and wish to develop R4A prints using AGFA chemistry. Agfa suggest that a liter of chemistry can process 38 sheets of 10 x 8. My tank uses 120mls per 2 sheets of 10x8 and because the delivery of chemistry is not very accurate (this I'm told by Jobo here in Australia is a problem even on the newer machines) by dialing up 110 mls, I end up using between 130 and 140 mls for each process. This means I'm using almost 3 times the volume of chemistry required. Should I seek to become more efficient by 1. Diluting the chemistry and increasing development/process times and if so would you have any idea as to the percentages 2. Reclaim the used chemistry and add it to the remaining fresh stuff, eg doing 6 processes, which would use about 720 to 750 mls, and then mixing it back into the remaining 250 mls and then processing another 7 times, giving me 26 prints, or 2/3 the maximum that Agfa recommends. 3. Find a chemistry which can be better used in the Jobo system (sadly Jobo chemicals are not available here) 4. other suggestions ;-) I favour trying number 2, but would prefer to find some way of using number 1 so that I continue to have one shot processing. Thank you for any help you can give me. - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
