Every method I have tried has advantages and disadvantages, what I have put on the web is designed to work well there as each image is saved as a single JPEG. My other techniques either require expensive hardware, or a complex setup before viewing.
These are Anaglyphs which means you need special glasses (around $6) to view them. Specifically you need Red/Cyan Anaglyph glasses to view these photos. You can order the glasses from many suppliers on the web, I cant recommend any one over another. However I do suggest that the little cardboard glasses will not be satisfactory for long.. I use the high dollar plastic ones! They work great.
Making the photos:
I use a Cannon S2-IS camera and take two shots from the vantage point of the left and right eye. I always take the left eye first, then the right eye, that makes processing them later much easier because you know which image should get what treatment. I use photoshop 6.0 to combine the photos into an Anaglyph. The script is easy to generate once you understand Photoshop. There must be other ways to construct these 3D results, and perhaps re-register the two images better. That is how I have done these.
Using Photoshop has the additional advantage I can tweak the colors in the resulting Anaglyph. Since I do this on my monitor I apologize if the colors are out of balance on yours.
I dont worry about the last picky details, for my purposes colors and registration just needed to be close, this is just fun!
