Several films processing at once

Matt5791 · Feb 25, 2006

I am going to process two 120 rolls of FP4 exposed at 100asa in Aculux2 1:9.

It is recommended to develop for 7.5 minutes. Should I consider increasing the time on the basis it is 120 and that there are two rolls? Or should I consider reducing the time on the basis I have exposed at 100asa?

I am using a paterson tank.

Thanks for any advice,

Matt.

Have you used the developer with FP4 before? If so, I would use the same time as you normally use.

You shouldn't need more time, just more developer.

Its actually the first time I have used FP4 at all - I've been on delta, t-max and tri-X.

I am doubling the quantity of developer stop and fix as per the instruction on the base of the Paterson tank ("each film uses - 120-500ml")

I shot the films today - portraits in the low winter sun.

The important point is how much developer stock solution does Paterson recommend per film? 35mm (x36) and 120 rolls have much the same surface area to develop so any recommendations apply to both.

Will your tank take two 120 reels or are you going to put both rolls of film on to one reel? If two reels then just double the amounts as you intend (making sure both reels are covered by the liquids). If both rolls are to go on one reel then you need to make sure there is enough developer stock solution for two films as I mentioned above.

Cheers, Bob.
