i had a good look at both these books in the bookstore last month (i spent more than an hour browing through both). practical poser 6 is a very good book (i bought it), while poser 6 revealed sucks dead warthogs through a thin straw, IMO. i don't know who their target audience is, since it's basically just a rehash of the documentation, proceeding at a pace that would bore a snail to tears. don't waste your money, unless you need to have tabs and buttons explained to you despite them being clearly labelled with their functions. it reveals such stunning things about poser as a full description of what you see when you switch to one of the rooms -- maybe blind people would find that useful? i didn't. no, definitely go for practical poser 6. it takes you through each setting, explains what the setting does, and when you might or might not want to use a particular option. it doesn't just offer a rehash of every basic tutorial on the web, but it also shows you specific details about trouble spots, and how to work around them. it teaches you how to achieve a realistic, natural pose, not the usual stiff-limbed display of newbies. and much, much more -- all of it in very clear language, and well-organized. it is not just the best book about poser i have seen, but one of the very best application guides, period. it is well worth the price.
