Pete: I use a developer of my own making that employs catechol. It is a staining type developer which yields tonal smoothness (and, yes, fine grain) much like PMK and DiXactol. And like PMK and DiXactol, it shows remarkably high acutance, thus it is particularly well suited to films such as TMX, which tend to look diffused in many developers. Acros has a look very much like TMX in terms of grain and sharpness, and it can also share its diffused appearance. In my developer, however, it appears very sharp, yet with a fine, smooth grain pattern that contributes to a very smooth tonal scale.(posted 8315 days ago)If you want to see the ethereal highlight separation I'm talking about, shoot some and run it in PMK. Then you'll understand. Otherwise, wait a year and I'll be happy to sell you some of my developer.
John: Thanks for the link. Damn that stuff is expensive! It's more than color transparency film.
