how much developer to use?

[scorpius73]

i use the patterson tank system for developing b&w film. the patterson tank calls for using 290ml for each reel of 35mm film to be developed. i was reading in the film developing cookbook, to use 250ml for each reel. so, if im using kodak d76 1:1. that would be 500ml for each reel. thats 210ml more developer. i just wanted to know if any of you use 500ml of developer and do you see any difference? ill try it out but i just wanted to know if you saw any difference. thanks.

i use what the tank calls for...10 ounces per reel.

I use Paterson as well. It says 290ml, use 300, it makes the maths easier. If your dev needs diluting 1:1, use 150ml dev, 150 ml water. Personally I use DDX, 1:4, 60ml dev, 240ml water.

Ditto what mpt600 said. I use DD-X the same way (1:4, etc.). IMO, 500mm per reel is overkill. Have fun in any case!

Or you can use even less by switching to stainless steel tanks (they need less solution to begin with). Usually 250ml per 1 roll of 35mm film is quite enough.
