Stereoscopy (also called stereoscopic or 3-D imaging) refers to a technique for creating or enhancing the illusion of depth in an image by presenting two offset images separately to the left and right eye of the viewer. Both of these 2-D offset images are then combined in the brain to give the perception of 3-D depth. Three strategies have been used to accomplish this: have the viewer wear eyeglasses to combine separate images from two offset sources, have the viewer wear eyeglasses to filter offset images from a single source separated to each eye, or have the lightsource split the images directionally into the viewer's eyes (no glasses required). Stereographic cards and the stereoscope. Two separate images are printed side-by-side. When viewed without a stereoscopic viewer the user is required to force his eyes either to cross, or to diverge, so that the two images appear to be three. Then as each eye sees a different image, the effect of depth is achieved in the central image of the three. Stereograms cards are frequently used by orthoptists and vision therapists in the treatment of many binocular vision and accommodative disorders.

This folding viewer for individual stereoscopic pictures has a cut-out between the lenses to accommodate the nose of the user. The original folding viewer was patented by J. F. Mascher of Philadelphia in March 1853 and was designed to hold stereoscopic portraits using the daguerreotype process. This was at the very end of the daguerreotype era, and originals are quite rare.Metal stereo viewer and many cards including stereoscopic photographs of crystal modals (Bragg's Crystal, Fluorspar, caesieum chloride, zinc-blende, iron pyrites, quartz, Tellurirumetc), and Dr Mullers Universal X-Ray Spectrograph. stereoscope, adam hilger, sir william bragg, w.i. bragg, dr muller, x-ray, crystal, spinel, bismuth, diamond structure, tartaric acid, naphthalene

The development of stereoscopic photography views or stereographs was immensely popular in the United States and Europe from about the mid-1850s through the early years of the 20th century. First described in 1832 by English physicist Sir Charles Wheatstone, stereoscopy was improved by Sir David Brewster in 1849. The production of the stereograph entailed making two images of the same subject, usually with a camera with two lenses placed 6 cm apart to simulate the position of the human eyes, and then mounting the positive prints side by side laterally on a stiff backing. Brewster devised a stereoscope through which the finished stereograph could be viewed; the stereoscope had two eyepieces through which the laterally mounted images, placed in a holder in front of the lenses, were viewed. The two images were brought together by the effort of the human brain to create an illusion of three-dimensionality. Stereographs were made of a wide range of subjects, the most popular being views of landscapes and monuments and composing narrative scenes of a humorous or slightly suggestive nature. Stereoscopes were manufactured for various price ranges and tastes, from the simple hand-held device introduced by Oliver Wendell Holmes who promoted stereography through articles to elaborate floor models containing large numbers of images that could be flipped into place. The stereograph became especially popular after Queen Victoria expressed interest in it when it was exhibited at the 1851 Crystal Palace Exposition. Like television today, stereography during the second half of the 19th century was both an educational and a recreational device with a considerable impact on public knowledge and taste. The Fine-art Photographers' Publishing Co. published many stereoscopic pictures from many different photographers from around the world under license. They also not only sold these images of various scenes and of famous people of the time but also were retail sellers of the viewers with the subject item having been made in the USA probably by H C White who held the patent for the subject items design from 1895 to 1902.An item that was very popular from the mid 19th century through to the beginning of the Edwardian period.

The Kromskop (pronounced Chromescope) is one of the earliest commercial applications of colour photography, and was invented by Frederic Eugene Ives and announced around 1896, it is described in his English patent of 1895 and in a US patent of 1894. It was shown at a Camera Club in Britain in January 1896 and at the February Royal Photographic Society meeting, and was available for sale from early 1897. The Photochromoscope Syndicate was formed in 1896 or 97 to promote the viewer in Britain, and wound up in 1899. It was manufactured in south London.A monocular instrument used to reproduce colours, in a mahogany box The viewer combines stereo images from three-colour separation transparencies called Kromograms, these are viewed through red, green and blue filters. A Kromogram comprises three monochrome transparencies printed from three-colour separation negatives which are taped together. The order being red image, blue image, green image with a label and caption between the red and blue images. The red image lies horizontally on the top step of the viewer above a red filter, the blue image lies on the lower step above a blue filter, the green image stands vertically at the back of the viewer. The red and blue images are reflected into the eyepieces by transparent mirrors, these are coloured to absorb the light that they reflect to prevent a double image from the rear surface of the mirror, the mirror for the red image is coloured cyan/blue, that used for the blue filter is coloured green (the patent indicates a yellow filter). The green image is illuminated by a yellow reflector. As the mirror below the blue image is green there is no need for a green filter immediately in front of the green image. The viewer can be used in daylight, for some conditions a diffuser is used, this is hinged to the yellow reflector and laid across the steps. An artificial light was also available. The mirrors and image positions can be adjusted in the event that they become misaligned.

After the invention of a camera that printed on paper in 1855, photographers started producing stereo prints on cards. These cards were made of two identical photographs placed in a 3D viewer. By looking throough the viewer with two eyes, one gained the impression of three dimensional depth. This early form of stereo photography remained popular until the 1930s.stereoscope
