Set of Glass Slides - Kromskop Viewer Set, Kromogram, Four Butterflies, About 1895 Image Reg. No: ST 023773 4

A Kromogram [three stereographic photographs on glass] of four butterflies. One of five Kromograms in original box to be viewed on a Kromoscop.

A Kromogram was produced by a special camera. A Kromogram was then viewed through a Kromoscop.

The Kromskop is a stereoscopic viewer which combined the images from six black and white transparencies through colour filters to creat a stereoscopic colour image. The six black and white transparencies were connected together in such a way that they could be 'draped' over the viewer. The set of six transparencies is called a Kromogrram.

To produce a Kromogram, the special camera took three pairs of images of a given object (an exposure time of a minute was required, which made it impractical for portrait work),

It used a combination of mirrors, prisms and colour filters, respectively red, blue and green on a single plate that measured 2½ x 8 inches.

The eventual positive was cut into three and mounted in a folded cardboard frame to form the Kromogram.

The three pairs of transparencies were black and white. However they differed in detail because they showed different features of the subject as transmitted through the particular colout filter.

The Kromskop itself, by an arrangement of mirrors, coloured glass screens, red, green and blue filters, and a light source, produced a full colour and stereoscopic image.
