Try a catechol based developer, I use my own formula on TMX 4x5 and it is great, also, ask Ted if he will sell you some of the formula he is creating, he has gotten very nice low grain sharp negatives with Catechol and tmx 35 mm, I have seen some of the prints and they are very nice.....(posted 8281 days ago)As opposed to Conrad's experience I have found TMX in LF to be a wonderful film, developed on catechol.
