Stereoscopic Imaging
Stereo Notes
- Notes for wearing anaglyph glasses - "red over right is wrong"
Stereoscopic images were around before regular photography
- 1838 - Charles Wheatstone wrote an academic paper in England that described the process for stereo images
- 1839 - first paper/invention of photography
Tips for working with anaglyph images
- when viewing anaglyphic images, it tends to work better if you work with a greyscale image and then create the stereo (red/cyan) effects
- values only, not hue or saturation
- work with a neutral color palette or a black background to reduce eye strain when viewing anaglyphic images; reduce UI elements as much as possible
Some problems to consider:
- Specular highlights and reflections are very tricky since they are view dependent.
- Retinal rivalry, crosstalk, and pinning.
- Horizontal image translation.
- Channel synchronization and alignment.
- Divergence - VERY painful!!

This class introduced the founding principles of stereoscopic imaging and it's applications, restrictions, limitations, and development in a variety of mediums. It highly encouraged experimentation to help the class further it's understanding of stereo and simply what works and what doesn't work.
All work was developed for viewing anaglyphicly using Red/Cyan (or Red/Blue) glasses since that was the best and easiest method to review the work during the development process. If you want to get your own anaglyph glasses, check Rainbow Symphony (they will also send you a free pair of anaglyph glasses if you send them a self-addressed, stamped envelope). I do still have the full color original sources if they are desired, I simply don't have a way to display or view them myself.
