A sample from the 4 mirror beam splitter device. I designed it with a fixed convergence angle which makes it relatively usable for portraits. At least for use in a DSLR, I thought maybe the reach should be enough to include one to several people, a foreground and several levels of background. So I set the angle to allow shoulders up close.

But I’m actually working on a way to adjust the convergence spot. I want to be able to have the narrowest central line and to have the same stuff on both sides so I don’t need to post process much. As is, you either get the exact same stuff on both images or you get a little more on the outside or on the inside. It depends on what side of the convergence spot the stuff is located. But its too much to ask, I end up cropping every time. Adjustment is the way to go.

    I would try to concentrate on setting the convergence at infinity and frame the nearby subjects so they are in view on each side. I tried adjusting this in StereoPhoto Maker but there are some strange distortions that I haven’t figured out yet. Show us some more examples please.

      Yeah SPM is really cool. I learned about it just as I was designing the latest version.

      The weird thing is that one might think that the angles should be 45. But that, what it does is it just gives you a full frame image…one half on one side and the other half on the other. The eye separation comes as the subjects get closer to you. I’ll post a few more.
