What is stereoscopy?
Stereoscopy, stereo photography or photography 3D is the technique for viewing of objects as three-dimensional using stereoscopes or stereoscopic slides. Stereoscopy give you the sensation of depth in an image.
People experiences the stereoscopic or 3D effect using their normal vision in nature because the binocular vision provided by the two eyes’ different positions on the head, therefore each eye see a different image of a object from different angle. This stereoscopic or 3D sensation can be replicated with two photographic images of an object taken from two different angles. The two images are then viewed with a stereoscopic viewer, in which we perceive the image as a single three dimensional image.
Side-by-side: two 2D images taken from different angle are viewed side by side with a stereocopic viewer.
Anaglyph: two 2D images taken from different angles and contain two differently filtered colored images, one for each eye. When viewed through the “color-coded” “anaglyph glasses”, each of the two images reaches the eye it’s intended for, revealing an integrated stereoscopic image
Lenticular: two 2D images taken from different angles are..
