rough estimate of 1000ml rodinal 1:100 8x10 sheet film usage?..

[Sean]

just curious if anyone has an estimate of how many sheets of 8x10 I could process with 1000ml of rodinal at 1:100? Wondering at what point I should refresh the chem.. Thanks

How long do you plan to live?

If you mean a solution of 1000 ml, my ballpark figures says four sheets, based on that I do four 35 mm rolls (36 frames) or 8 sheets of 4x5 in that amount of solution. But then again, I don't develop 8x10 so the figure may be off the wall - I am just extrapolating...

Sean,

that's a tricky question.

I read that you will use 10ml of Rodinal. That would be enough for, say, max. 2 sheets. I'd suggest stand development for that.

Best is to try it.

One thing that is sure: discard the solution after use. Rodinal is a one shot developer.

I usually do 4 4x5 sheets at a time with 7,5ml Rodinal in 2000ml water. 1 hour total, 1 minute initial agiation, again about halfway development time.

Greetings,

How do you keep the 4x5 sheets in the water, avoiding contact between each film?

Tom,
is that adressed to me?
If so: slosher tray.

Yes.

Question for stand-development afficianados... is stand or semi-stand normally done with the film vertical, like in hangars, or horizontal, like in a slosher?

I would make that calculation the same way Jerevan does, but if you're doing it in 11x14" trays, shuffling rather than doing stand development, you'll probably want more like 1.5-2 litres just to have enough solution to work comfortably.
