Hi

The thing is that the human eye has a very wide field of view.

While I'm sitting here looking at my monitor I can see things at a greater then a 180 degree field of view.

The verticals are still vertical even in the corner of the room almost 90 degrees from where I'm looking.

When you do that with a lens you get distortion.  Lines curve, the verticals go off things look like a fishbowl.

Your eyes don't do that because your brain processes the image.

I'm an example, I have had eye surgery on one eye, and I will have the other eye done this summer.

I can see well out of one eye, really poorly out of the other.

But I can still see better with both because my brain combines the two images the bad and the good and comes up with an image better then either.

I will experiment with focal length to see what effect it has on stereo images as soon as I have time, I've never thought about making a fisheye lens kind of 3D image.

But it will be easy to set up a scene and then make right left images with different focal lengths.

If you shoot a mime, do you need a silencer?
