CAMERON’S 10 RULES FOR GOOD STEREO
1 There is no screen
2 Stereo is very subjective
3 Analyzing stereospace on freeze frames can be misleading
4 Convergence CANNOT fix stereo-space problems
5 Convergence is almost always set on the eyes of the actor talking
6 Interocular distance varies in direct proportion to subject distance from the lensshots
7 Interocular and convergence should both vary dynamically throughout moving shots
8 In a composite, the foreground and background may want to have different interoculars
9 When stereo looks bad to the eye (visual cortex) it is important to eliminate the problems sequentially:
Sync, reverse stereo, Vertical mismatch, color/density mismatch, render errors, highlights, image warping, vibrations
10 Some shots just can't be fixed
