After studying David Armstrong‘s work, I was intrigued by the sense of a third dimension and depth created in the layers that build through the image. Although this does not directly link with the alliance of the eyes and the brain, the perception of 3D and 2D images does.
Stereoscopy is described as a technique that ‘enhances the illusion of depth’ created by the offset of two images (which relates to my earlier Strabismus work) and the viewer perceives the image with both their left and right eye separately. The brain then combines the two-dimensional images to give the perception of a third dimension. This is a strong link to the alliance of the eyes and the brain, so I plan to use 3D photographs as a visual representation of this alliance.
Traditionally, stereoscopic images were created using a pair of 2D images (a stereogram) (below).
This was a simplistic technique to enhanced depth perception in the brain by providing the eyes of the viewer with two different images, representing two perspectives of the same object, with a minor deviation exactly equal to the perspectives that both eyes naturally receive in binocular vision. This is very similar to the images I produced for my Strabismus study, yet interestingly those who suffer from Strabismus or Amblyopia (two of the sight deficiencies I explored) often cannot perceive 3D images.
