I'm amazed at the responses in this thread. If such an extra wiiiiide variety of different results can be had with a single film-developer combo, then what's the point in a film forum at all?
I'm sorry but it's all bullcrapola: consistency and repeatability is the name of the game. If your results are different, even slightly, it's probably time to get serious. The whole point of concistency is to be able to control the only thing you can control.
To the OP: I too would love to know the details of each photograph in a book.
It would be really helpful and it would make me really happy trying to analyze them with those infos in mind.
