Bought this book, this is a fantastic resource for the aspiring and established matte painter.
The workthroughs are so detailed it does not leave you behind, the video that came with the book also is a good resource.
If you are after a good book on the invisible art then this will be in the trinity of books that I keep on my bedside table, The invisible art by Craig Barron and Digital Matte painting 1/2 by ballistic media has a worthy contender.
I almost bought this book yesterday, I carried it around chapter's for a bit browsing through it, got to the register and realized I forgot my debit card.. got to wait until tomorrow now. I am REALLY REALLY impressed with everything covered in it, I can't wait to get this book :)
