Scope and content

Item is a Kromskop viewer developed by Frederic E. Ives in 1895. Item comes with 1 monochrome transparency made from 3 colour separation negatives layered together; these transparencies were often referred to as kromograms. Kromograms were known as early examples of colour photography available as both mono and stereo images. A glass monoschrome plate is placed on top of object, when viewed through glass eye holes the image is overlapped with three kromograms making the stereograph appear three-dimensional and coloured. It is built in a staircase-shaped box with two eyeholes on the front. The articulated base allows the viewer to be properly oriented with light. At the back of the object is a tilting mirror. The mirror is designed to redirect light into the virtual window above. Lighting can be controlled so that the colour will not be distorted and take on a dominate colour.
