I've developed Foma in Rodinal (1:50), HC-110 and Tetenal Ultrafin, works well in all of them, very nice tonality to it.
The nicest contrast I've gotten out of fomapan 100 so far, is in Rodinal.
If the scans look washed out, remember to set your black and white points on the level adjustment slider first and foremost, after that you can play with the middle-gray slider to get the contrast you want.
- Some people prefer the curves-tool, which basically is the same thing, only a bit safer concerning black and white clipping, it also gives you better control over the contrast adjustment.
An clear, upswept curve on the landscape scan makes it pop nicely and pulls down the sky a bit, and a very slight "S" shaped curve on the portrait, makes that one pop really nicely also.
