OK, here's the El-Cheapo stereo viewer system that anyone can make for very low cost. I got this idea from the "ViewMaster" stereo viewer toy that I used to have when I was a kid.
What you need are 2 pocket slide viewers. Stick them side by side using double-sided tape as shown in the pictures below:
Next, you can start taking stereo pictures on normal 35mm slides.
Look for a scene that has objects at differenet distances from the camera. Pick a point in the scene to be you centre of focus. Place that point right in the centre of the frame. Meter and take the first shot.
Keep the same exposure settings, move the camera about 8 centimeters (about the separation of our 2 eyes) to the left (while maintaining the same height), and place the point of focus right in the middle of the frame again. Take the second shot.
Now you have 2 shots of the same scene taken with a slightly different perspective.
Repeat for other scenes. When finished, send the slides for processing and mounting.
To view the slides, pick a scene and place the slide taken from the right side perspective into the right slide viewer and vice versa. View the slides like viewing into a binoculars.
You should be able tto tell the left and right slides from the perspective. Otherwise, make sure you shoot the left anf right slides in the same sequence for every scene, so that you can differentiate the left and right slides by the slide number (odd or even).
I could not show my slides here, so I took some shots with my CP995 to demonstrate the left/right perspective:
If you know the parallel-eye viewing method, you should be able to view the pictures in 3D right there on your monitor.
Using a focal length of 45mm will simulate the actual angle of coverage of our eyes very well. However, you do not have to be limited to using only this focal length. Experiment with various focal lengths (even telephoto) and the results are usually very good.
Let me know if this works for you.
Thanks!
