Thanks for all the answers, everyone. It's kind of surprising that there is no single site that describes all the different transparency viewers. George: What are Realist ear viewers? Are they like he

It is not very comprehensive because it doesn’t have the Realist brand US viewers, the major 3D camera/viewer manufacturer in the US. Stori-view and Tru-View are coming. The Wollensak is pictured, but

Yes, Ray is correct, the lenses are different. For one thing, there is a slight difference in focal length, the Wollensak lenses are a few mm longer (smaller image), I think 47mm vs. 45mm for the Reve

I am volunteering to organize a resource for the community; a collection of stereoscopic images that could be used as standard test images. Basically our version of "Lena" or a "china doll" and a vers

You have brought up an interesting and important topic -- how to report errors in the metadata, and to whom? One of the problems we have to deal with are the levels of indirection. In the provided met
