Got a chance to play with a live 3Ality rig in Bexel's booth today. Learned you absolutely don't want to change interocular within a shot but convergence can be pulled creatively. There will come a day when the audience is so used to 3D that it will be possible to pull convergence to change their attention point much like pulling selective focus is used currently. Great thing about pulling convergence is that it works very nicely with deep focus.

Hi Hal,

I've done this a few times. Its particularly effective doing this with a vertigo shot. Much harder to do with physical camera of course and if you don't want to noticeably stretch the depth you have to have a distinct kind of shot to use this on. e.g. going from a long shot to a close in shot... "flying over a bunch of bunch of buildings then flying down to see our hero walking along the street.. camera ends up framing his face". It is possible to smoothly transition from showing the depth of the buildings to the depth for a closeup.

but generally you wouldn't want to do it...
