Wow, nice system! But the price ain't for the faint of heart :)

I don't get it... what exactly does this do? I don't see anything particularly out of the ordinary about the sample videos. They certainly don't look more '3D'.

I remember this from researching 35mm adapter tech from 2004. I wasn't impressed then, and not impressed now. They should do some before and after shots to attempt to showcase what this is all about. To me it just looks like nicely shot 1/3-2/3 chip HD footage. I'd say you get more essence of 3D from the gimbal stabilizer work seen on their examples.

I recently attended a talk by V3. Years ago they found that you get a 3D effect by taking two photos side by side (like stereo), then switching between them. They found a 4.3 Hz rate to be optimal. You can take your own photos, put them on a timeline, line up the subject of interest, loop and test.

This basic approach is harsh. Rather than switching, if you can wobble the camera position in a sine-wave motion, it's more acceptable. One problem is that much of the time, the camera position is in the middle. The next evolution was a circular motion. That gives both vertical and horizontal perspectives.

Their first prototypes moved the whole camera/lens. The latest version moves just the aperture.

I'd be curious to see this combined with stereo 3D. In the real world, we get 3D cues from stereo as well as the movement of our head/body. For instance, when we walk, we bob up and down.

Motion persistence and 3D are real. Birds with eyes on the sides of their heads lack foveal stereo vision, yet they can land on tree branches and telephone wires.
