When I was in college in the Art Department, I was studying the 3-D effect and made drawings of the blue-red type of 3-D images that use the 3-D
glasses. That was somewhat tricky as the spacing of red vs blue drawings would determine the distance the lines would come forward or recede. I then
went on to make a stereopticon (AKA stereo viewer) and created stereo images with a single camera.
The process was fairly simple. I mounted a small bubble level on a camera tripod and marked it for camera placement about 2 & 1/2" apart, the average
distance between human eyes. I would take a picture from the left and then the right on a focus point of the subject. When I developed the photos, I
enlarged them to the size meant to fit in the stereo viewer. It worked really well.
The next step would have been to colorized the photos red and blue to use the 3-D glasses for the effect. I never took the process that far, but with
computers, scanners, and digital cameras, it could be done fairly easily these days. Back then I developed black and white film and enlarged the
photos in my own dark room. I could have used a computer to make the red/blue images, but the professors weren't very interested in 3-D back then. Of
course now the 3-D effect is used in movies all the time. I was usually about 20 years ahead of those guys back then, unfortunately that never helped
my grades at all.
