Very helpful review in context (of the key older works). Thank you, Chris Walrath!
Looking for good info on Split Grade Printing and working B&W with color enlargers, I found Chris Woodhouse's PDF chapter on splitgrade and ordered the book straight away. Just skimmed it fresh in from Amazon yesterday. This is a book written in the spirit of imparting information (rather then establishing authority). Very clear and complete.
It's definitive. Everything you say, Chris.
