>>Lastly, I was hoping that someone could provide some feedback on the speed issue, it'd be nice have an inkling of where this 50 to 100 ISO range stands in reality(posted 8933 days ago)Check out Gene Crumpler's posts here and at photo.net. He claims a true ISO of I think 100ISO with Diafine. He seems to have a lot of experience with TP, having gone through a large number of developers trying to dial it in to his taste...
But with my experience, which is with PMK and Technidol, TP does not go gracefully with even 1 stop underexposure.
