| Stereo Photography has been around for about 150 years and the UK's
Stereoscopic
Society has been around for over 100 of them, but most people
remember stereo as anaglyph (red/blue specs) movies from the 50's
or the Red ViewMaster Viewer which works with discs of seven stereo
pairs of slides. I started taking stereo pictures in 1991 after a
one day holography class by Martin Richardson at the Royal College
of Art and have gone on to use the technique in computer based 3D
modelling and animation. Have a look at Stereoscopy.com
for more things stereo. |
  
| Every stereogramme is made up of two images, one for each eyes point
of view. At first glance both images look identical but for standard
stereo the left and right camera lenses that produce these images
are separate by around 70mm or normal eye width. Looking at the results
in a stereo viewer replays the correct information into each eye which
allows the brain to extract the magical spatial data recreating the
scene as if you were standing there. |

| My own stereo camera is called an RBT
and is engineered in Germany from two Ricoh SLR's. The 28-70mm lenses
are coupled for zoom focus and aperture and it shoots 18 stereo pairs
on a 36 exp 35mm film. For this to be possible it first exposes one
pair with a gap of one frame in between then winds on a frame and
shoots another pair. Four frames of film are now exposed so the next
wind clears three frames before repeating the 1-3 cycle. |

| After normal processing I either project the slide pairs on a silver
screen with polarised filters and polarised specs or use Jim Sharp's
excellent Pinsharp
viewer for hand viewing. |
 
| I have over 200 stereo pairs in this gallery running in chronological
order. You can choose to freeview a stereo pair, look at the mono
version or get your red/blue specs out for the anaglyphs. |
