Hi all
Is it possible to do stant development with every kind of developer, say perceptol,atomal,d76,d23?
What specifications must have the developer for this kind of developing.
Thanks too much

Riton, What you need with a stand development developer is one that exhausts someone linearly. In other words, you want highlights (the densest area of the negative) to not overdevelop because the developer is still very active. As the developer exhausts, it has less effect on the highlight area of the image, while having an effect on the shadow area.

That said, D76, D23, and the like, are very active developers, that do not exhaust easily. Look to developers like Rodinal, Adonal, and HC-110.

Thanks Michael,but can active developers be highly diluted say d76 with 20 water?

Even though I don't deem it too promissing to do stand development with D-76, I'd start with 1+9 at 18°C. 45min maybe. Riton, what is your goal or problem you want to solve with stand development?

Hi PC
Generally I put several films with several iso 1 hour.I expose for half declared iso say ei 50 for
fp4 and ei 200 for hp5.I do generally lanscape photography and with stand I hope to manage the contrast.I have more accutance also and I use 120 roll film.Last night I mixed 50-50 rodinal with hc110 and added water to make dev-water 1-100.So 5ml rodinal,5ml hc110=10 ml and 1l water.Put the timer for 1 hour agitated first minute and went home to return 1 hour later.BUT I was sleepy and slept for 2 hours.Returned to darkroom, fixed the film etc and well 75% of frames were contraty and not only usable but capable of good prints.Yes that's all
