Jim, I just started looking into "rolling my own" and the DCB (second edition) is my starting point. Is it really that bad? I am mainly interested in making relatively simple paper developers, fixers and washing aids.
People on the internet have a habit of slamming books for even tiny errors which affect 0.01% of the readership, if that, and this creates the impression that these books are riddled with errors. Both the Darkroom Cookbook and the Film Developing Cookbook are fine books with more formulas and fewer errors than any comparable resource you can find out there. I bet you can make a working print developer from 99, or more likely 100% of the formulas published for this purpose in any edition of the DCB.
Trying to be the best of whatever I am, even if what I am is no good.
