Here I am making a nuisance of myself yet again...


1) I use X-TOL 1:1 and Microdol-X 1:3 for 90% of my processing.

2) The Kodak literature specifies 100ml of stock solution per 80sq.in. of film (one 35mm roll).

3) The Jobo tanks (2500 series) for the ATL-1500 hold a maximum of 660ml for five reels.

4) At 1:1, the total volume would be 1000ml; at 1:3 it would be 2 liters!

So, it's impossible to process 5 reels at these dilutions, unless... and here, finally are my questions:

Is it possible to lessen the stock solution and lengthen the developing time?

Is there a formula for figuring out how much to lengthen the developing time?

Thank you in advance for your help.
