I think you should not use rodinal for developing TMAX films , Because the great advantage of this kind of film is a very fine grain, and rodinal makes large grain. I've already tryed TMX in rodinal, an I obtained a very irregular grain. Use better TMAX or XTOL developers for T-grains films. If you want to obtain a bit more grain, better use classical technology film as PLUS-X or TRI-X... More, I find the grain of T-max films fuzzy, and I prefer the sharper grain of classical technology film.(posted 9517 days ago)(Sorry for my bad english)
