linear compositing workflow, down & dirty

Master Zap of Mental Images gives a very interesting talk on linear colorspace in a visual effects context with a bit about workflow, and all the nerdy bits in between in this spectacular FXguide podcast with Mike Seymour.  Listen in here.  Of course, Stu Maschwitz of Prolost always has a lot to say about linear color workflow in After Effects, some of which you can find on Prolost.
