Quote - The script for image generation creates left and right images for parallel cameras. Compare to Hairy python script, this script offers a choice of the stereo base (distance between cameras) but the setting of the stereo window should be done in Stereo Photo Maker. In Hairy script, the stereo window is set by the convergence of cameras (not a bad approach).

The convergence issue has been something I’ve found out about from using my stereoscopic camera. On that (it’s a Fuji) you can adjust what it refers to as “parallax” - or stereo base. The problme with doing this post phot taking is that the image starts to be cropped width-wise as image data that won’t be included in the 3D image gets lost. I find this if I import my MPOs into conversion software and make the same adjustments there.

I have seen a lot of images out there which are very hard to look at - you really have to force your eyes to “see” the 3D, and most of the time it appears that this has happened because the stereo base has been adjusted so much that it starts to be meaningless to your biology (ie the distance between your eyes). I am a firm believer that there should be no eye strain at all, and that when you drop the red/blue filters over your eyes, the scene should “pop” without any extra work needed.

This has been my approach - keep the left/right cameras within a comfortable distance for the viewer (and for this, I mean the distance should be fairly close to the physical distance between your eyes), and let them do what your eyes do naturally to generate a 3D image in your brain - that is to swivel inwards to a point (usually the point of focus). Your brain then gets the two pictures and snaps it into some kind of sense.

That’s the methodology behind my scripts - trying to keep it as comfortable as possible for the viewer.
