Do-It-Yourself 3D Stereo Slides
Stereo slide aficionados could make their own stereo slides. All they needed was a stereo slide camera. After getting the stereo film processed, they would use these special do-it-yourself stereo slide holders.
How DIY 3D Slides Worked
The films could be slid into the slots—one on the left and one on the right—easily accessible without tearing the holder apart.
Taking Stereo Pictures Without a Stereo Camera
Stereo pictures could also be taken without a stereo camera by:
- Taking one shot
- Holding your position but moving the camera left or right about two inches
- Taking another shot
This simulated what would be seen out of the right and left eyes. Our eyes see in "stereo"—the pictures are taken from different perspectives. Put the processed films into these special holders with open slots, then put the 3D slide holder into a viewer, and you have a 3D stereo view that has depth.
