I've shot quite a bit of Acros, developing it in my own catechol developer. It's tonality is outstanding, with a slight flattening on the shoulder. In many ways its like TMX in terms of grain and sharpness, and like TMX, it can look diffuse if processed in a fine grain solvent type developer. I haven't tried it yet, but I would bet Acros would look great in Rodinal @ 1:50. It seems to me the two are a perfect match. Try using the same times you find for TMX. That should put you pretty close.(posted 8291 days ago)
