Please understand that I am not trying to stifle anyone from contributing - the point of my last thread is that we have 1.3 million threads here on APUG and maybe a half dozen are on the philosophy of photography (I mean that in a formal sense, not the generic "we have a philosophy of care in the hospital" meaning of the word). Nobody ever suggests when people are discussing agitation cycles, pre-rinse procedures, stop bath preferences or exposure logs that this is somehow not real photography and that they should stop these discussions and just take pictures. For some individuals, understanding how a developer works on a chemical level helps them take pictures since they know what is going to happen before they hit the shutter - for me, understanding why I am taking the shot is what helps me fire the shutter.
If we have contributed to someone being more curious or thinking more deeply about something, then it is worth it. I probably won't get around to reading the book till next week but it is nice to be able to have a discussion.
