So much for chineese science. Anyone wanting to see the destructive
habits of JPG to stereograms (anaglyphs) are invited to visit:
http://hjem.get2net.dk/stereoskopklubben

The ghosting you see there on the JPG's is not present in the original
PNG anaglyphs. Is there a browser where you can import PNG ?
I will not use the stereovariant JPS if it can be avoided, because it
has the same problem, allthough not so grave viewed with DepthCharge.
By the way - where can we (Stereoskopklubben) get the proper red/cyan
glasses ? That is glasses with filters matching a modern monitor ?
