Diafine

[Ronald M]

Diafine and tri x seems popular at 1200/1600.

Has anyone done a proper film speed test with this combo, like using a step wedge or densitometer to measure shadow detail ?

Can't be of much help to you on the densitometer front, Ronald, but I can say that I've never had a problem with shadow detail rating the film at 1250 ISO. Grain for this film speed is also excellent. Maybe someone who is more technically-minded will respond to this bump.

There are a couple threads and some tests of Diafine from a number of years ago here at RFF. If I find them I will post a link, but do a search. You may find them before I do.
