Hi I was wondering does anyone use rodinal as a paper developer? What's the concentration that is used? Is it like 1+31?

Thanks

Agfa calls Rodinal a "Black and White FILM developer" - I don't believe it's ever been intended for paper developing. It goes bad very quickly once it's exposed to air, so it would die in the tray within an hour or so.

But if you want to try it, print developers are usually MORE powerful than film developers (since they have to do their work in 3 minutes instead of 8), so you probably need a very concentrated solution - more like 1+10 or 1+15.

I tried 1:20 and 1:15. Neither was strong enough for my taste. Rodinal is probably only suitable for very low-contrast requirements as a print developer.

I've spent quite a bit of time studying both film and paper developers, and I've never seen a formula for a paraminophenol paper developer.
