I am an 83 year old retired photographer and I have been shooting stereo slides since 1953 with the same Stereo Realist camera.\nThat is until a few years ago when film and processing costs put a strain upon my Social Security check.\nWhen I can get out and around I now shoot with one of my two 3D camcorders, although that means sacrificing resolution for 3D.\nI have recently acquired a Vizio 42 inch 3D HDTV. Vizio uses the passive system which utilizes polaroid glasses. I have an active shutter glasses system from some years ago, but it will only work with some Cathode Ray Tube TV sets. However, I prefer the Polaroid glasses system which is much cheaper and since I wear glasses anyway (who doesn't these days?) clip on 3D glasses are like not having to wear 3D glasses at all. Since most people do wear glasses these days I cannot understand why they balk at having to wear 3D glasses to view a 3D movie since clip ons eliminate the problem. That is, unless you prefer the ridiculous cost and added weight and complexity of shutter glasses as well as wearing glasses over glasses.\nBut I see that I am rambling. I hope that this somewhat introduces me and I look forward to becoming a part of the forums.
