Yeah I have it. I'm only about 100-150 pages into it, but it's pretty good. The digital stuff is ok - there are probably better resources out there for most everything they talk about. At the same time, they aren't droning on about photoshop techniques or anything, so it's not just novice rubbish.
As far as the analogue side of things go, it's pretty good to very good. I got it when it came out for I think $50, which is a great deal in my mind for a big hard cover book on a niche topic. It gets in to some advanced topics.
I'd say if you do analogue printing and can spare the money, it's definitely worth it. If you don't wet print, it's a waste. And if you don't have the money, well, it would make for a nice Christmas present 🙂
I find it MUCH better than say, Thornton's 'Edge of Darkness'. That book wasn't all that great in my mind, even though I see it gets recommended a fair amount. Other books that are/were cheaper that I might recommend first are Vestal's two books (dirt cheap used, like $1-2), Les Mclean's book (I thought $20ish new, but you can get it used for half or less), or any of Tim Rudman's books ($25ish new, but some are out of print now and rapidly climbing in price).
