Alberto, I'd never have thought of just hand-holding and shooting twice! I also have a cross-eyed 3-D page for digital and disposeable cameras: http://www.panoramacamera.us/autoshow-09stereo.html One can easly catch on to cross-eye vision with a little practice. It requires only a slight amount of crossing and the eyes need to be relaxed and level with the image. Once you get it it is easy thereafter. AZ LOOKAROUND - Since 1978 Build a 120/35mm Lookaround!

They had an aerial photo under a stereoscope. I was so impressed that I wanted to do something like that, but I never actually get a stereo camera nor stereoscope (but I did some rudimentary experiments with hand-held mirrors - in retrospective, I could have cut my nose *blush*).

However, stereograms retain full and faithful color information. Besides, I discovered that "wearing" a red 25 and blue 82B filters do not help much in the computer screen (the blue isn't right, and besides my monitor is quite off, I discovered). > > > > I do my El Cheapo stereograms shooting hand-held and just stepping to one side for the second picture. High resolution allows me for some error (so I can crop the images) and with digital technology I can have them pretty easily. So far I have been doing close scenes (indoors, or statues) I change the angle of the picture slightly to get the "cross" effect. I put the images in one file, one next to the other in photoshop and voilá! > > > > The only sad part is that not everybody can watch them until they master their cross-eye technique (and you have to be careful for distracting reflections on the screen surface).
