A Stereoscopic View Adds Depth


StereoscopicAn English inventor, Sir Charles Wheatstone produced the first means for displaying 3D images. It consisted of a viewer with paired lenses that allowed an observer to examine two slightly different pictures positioned side by side and thereby created an illusion of depth. Later, with the advent of photography, cameras with two lenses recorded two simultaneous images and, once developed, the paired photos were loaded into a special viewer producing a stereoscopic effect.

Still later, sets of these paired images, known as stereograms, were compiled around places of interest and special events to be sold as souvenirs and were widely collected during Edwardian times.

From The Power of Love to the Magic of Avatar

It is unlikely that anyone reading this will remember the first 3D movie shown to paying audiences in 1922 and entitled “The Power of Love”. The flirtation with this type of entertainment continued and many differing methods were used to achieve stereoscopic images.

Anaglyph format using red and green lenses for viewing was the earliest working technique, progressing later to Polaroid lenses that were far less prone to causing eyestrain and headaches on prolonged use and simplified the production of full colour features in 3D.

The effects, however, were a far cry from the stunning realism experienced in 2010 when moviegoers were privileged to share in the role of an avatar on the alien world of Pandora, and further still from those early stereoscopic photos.

And Now at Home Also

Several differing means for creating and viewing 3D moving images have since been developed but the most significant advance has provided the freedom to view 3D features on a large flat screen TV in the comfort of our own homes.

Sets are now widely available in either full 3D models or 3D-ready models that require a set-top unit to become operational. Both utilise LCD shutter glasses that receive a signal from the TV controlling which eye can see the current image. Still under development, sets that require no glasses may soon be available.
