Fxguide's 'Art of' Tracking, Keying, Roto, Optical Flow, HDR, 3D Stereo, & more

Fxguide's 'Art of' series is still pretty good. Here's what's easily found in the series:

• The Art of Tracking
• The Art of Keying
• The Art of Roto
• The Art of Wire Removal
• The Art of Optical Flow
• The Art of HDR
• The Art of Digital 3D Stereoscopic Film
• Matte Painting: 1, 2, 3, 4

Covering some of the same ground is "classic" VFX training resurrected for now on Vimeo, the out-of-print Masters of Visual Effects.
