Stereo Photography is as old as photography itself, even a little older. The first idea of 3D photographs is as old as 1838, but daguerrotypes weren't too well suited for this, due to their high reflectivity.
Many methods have been developed in time, and carried on with more or less success and application in real life. Worth to be remembered are the 3D movies in the Fifties.
The ANAGLYPH STEREO system, the one with the Red/Cyan (or Red/Blue) glasses is one the most commonly used (although being one of the most imperfect), and doesn't require much equipment to work, just cheap glasses.
Anaglyph viewing can provide, besides the Z-axis view, a very interesting shape-decomposing image and an extreme perception of shapes without the glasses, and a returning "depth-normal" image once the glasses are on again.
The analysis of what the left-right side of our brain perceives, along with the resulting pre-fabricated sensation of depth are highly satisfactory, and give the viewer that extra information to destabilize his/her judgment, and to seek for the missing elements. Brain illusions, welcome to 3D Stereo viewing.
These galleries will show different results I obtained with the use of two digital cameras, some Photoshop tweaking and enthusiasm. You can move in the galleries clicking your mouse or using "N" or "P" on the keyboard.
The images have been taken with two digital cameras, hand operated (but not synchronized for now) and optimized for the best viewing with cheap Red/Cyan glasses. The use of more precise Red/Blue glasses may reduce or eliminate ghosting in most cases.
Enjoy!
