The other day at the MCBA Visual Journal Collective a group of us stayed to chat and Tom Winterstein mentioned he really liked Walt Stanchfield's Drawn to Life books (there are two volumes—that I know of—in paperback from Focal Press).
I think I've written about these before, but my search engine isn't working for me again today (something in the way I set up my browser). It can never hurt to mention them again.
I picked up volume 1 when it came out in 2009 and have been reading it (and volume 2 when it came out) as time allows. The books are lecture notes—short little pieces on a specific drawing-related topic from curves to "Pose and Mood Plus Timing and Phrasing and Texture."
Each piece is a lovely little gem with great illustrations of the topic at hand. Stanchfield was the artist Disney asked to teach other Disney artists. These are the master classes.
I am constantly entertained and inspired by the topics he addresses. I see these as essential discussions for all artists, not just animators. The purpose of art is to communicate—who better to tell you how to communicate than someone lashed to the narrative tradition?
(I paid $30 for each book, but Tom mentioned he got them for $14 or so at Amazon—check around.)
