The chromoscope is a device for direct viewing of three-color slides according to the additive method. Each slide is illuminated through colored light filters in red-green-blue and brought together optically using semi-transparent mirrors. This type of photographs can be considered the first color images. However, they were not fixed and could only be viewed through the apparatus.

This chromoscope belonged to John Hertzberg and later Helmer Bäckström when teaching photography at Kugliga Tekniska Högskolan in Stockholm. "Prof Dr Miethes Betrachtungs-Apparat", chromoscope for viewing color images is based on the first practical breakthrough for viewing color photography invented in 1891 by Fredrich Ives (1856-1937), in Philadelphia. Three negatives, one in each primary color (green, red blue) on a single plate. The slide was made directly from that plate and viewed in an apparatus that Ives called the "photochromoscope."
