If anyone is interested, here’s a 25% off discount code for Routledge Books, who distributes Focal Press Books and The Film Developing Cookbook by Troop and Anchell.
The Film Developing Cookbook by Troop and Anchell. That's the bible for developers, even if you don't mix your won chemicals. Lots of useful information.
Yes, it's a great reference, but don't accept everything it says as chapter and verse, especially with respect to newer film technology and materials. There are a number of anecdotal and speculative perspectives included that don't seem to square with what many others have experienced.
