Shortcuts About Stereoscopy (Stereophotography)

Stereoscopy: Photography And Binocular Spatial Perception (Stereopsis)

photographic technics
spatial depth
the viewers capabilities of depth perception (seeing with both eyes and the spatial cognition by your mind)

spatial contrast (depth contrast)
the need of 2 images simulating two eyes: left and right image from a slightly different position (eyebase – stereobase)
the stereospace should be taken synchronic
the space of depth in a stereogram depends on focal length as well as stereobase
has it’s own rules for exploring and capturing the space

erasing the insufficiencies from capturing
- geometric, e.g. vertical alignment, rotation
- images, e.g. brightness balance …

postprocessing for presentation
- geometric/stereoscopic conditions
  - presenting methods
  - presenting size

analog and digital possibilities
- corresponding equipment for presentation, e.g.
  - correct prints (e.g. calibrated colours for anaglyphs)
  - lenticular prints
  - stereoglasses (anaglyph, digital: active and passive)
  - stereoscopes
  - digital screens, lenticular displays, active and passive stereo screens
presenting methods and equipment
- most presenting methods need equipment (stereoscopes, stereoglasses, special 3d-screens…) or printing issues (e.g. lenticular)
- without equipment possible, but need experience
  - parallel view for small images (image centres of left and right images positions less or equal eyebase (stereobase) of the viewer (<~6-6.5 cm)
  - cross view
the place of presentation
- the size of the presentation
  - stereoscopic conditions
- distance of viewing
  - the more distant you are, the more depth you see
