Response to changing minimum variables for finer grain & acutance

Agitation certainly matters and you can probably see a contrast difference by adding or subtracting just one inversion per set. Watch your temperature too, including the wash. Gross changes lead to reticulation, but that doesn't mean that smaller changes have no effect. Grain is actually clumps of grain and supposedly they're affected by temperature change and even the way the film is dried. There are some interesting errors that can occur with grain focusers- look for a copy of Ctein's Post Exposure at the book store. He covers a bunch of things you might find useful. BTW, you probably wouldn't notice the things you're seeing if you were using multiple films and developers, so the stratagy has proved itself sound!
