Issues with Stereoscopic Images : Introduction

• We are dealing with Stereopsis, not 3D.
  • But these images will take advantage of both stereopsis, and vergence
  • So there is a 3 dimentionality to eye movements in these images not present in other images.
• First method of stereoscopic images is 1832, using mirrors by Wheatstone. Incedentally, the first method of permantly capturing an image with a camera is 1839 (Daguerreotype). (Hirsch, Seizing the Light, 2000).
• Some Common Ways of Viewing Stereosocopic Images
  
  Above see : Front Row: Prism Glasses (side by side), Brewster Stereoscope (also prism as is viewmaster), Middle Row : Chromadepth (interference filter), Anaglyph Glasses (Cyan/Red), Back Row: LCD Shutter glasses (3D displays at home), Polarizing Filters (movies).

• Civil War Stereoscopic Images and Jitter Presentation
  • Jittering the image uses motion parallax to create the impression of depth.
• So with this long interest why not more stereoscopic images and movies?
