Morning all, Here's a gallery of cross eyed 3d experimental work I have done in the past. http://www.andrewbrooksphotography.com/view-archive.php?id=13 Thanks, Andrew > Date: Mon, 1 Mar 2010 17:46:02 -0800 > From: fotodiseno2003@xxxxxxxxx > Subject: Pseudo-3D > To: photoforum@xxxxxxxxxxxxxxxxxx > > Hello everybody! > > Just a short note to let you know about my most recent photo experiment. > > Several years ago I was at a science fair in Tucson and I saw for the first time a stereogram. 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*). That was way before Al Gore invented the Internet and so I eventually forgot about it. > > Quite recently I came across some stereograms on the net and I realized that I could look at them in all their 3D glory if I cross my eyes. Soon I was doing my own, and I haven't perfected the technique, but I am quite satisfied. > > A widely known technique, the Anaglyph, is a 3D image that requires bi-color glasses (red and cyan). 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). But so far, I am happy. > > Hey, perhaps I can prepare a conference for RIT sometime! ;) > > ********************** > www.alberto-tirado.com > > > > |
