100. Ives's three-colour stereoscopic 'Kromogram', c. 1895
Frederick Ives's commercially produced 'Kromograms' of 1895 were the first colour photographs available to the public, and had to be viewed through coloured filters using his 'Kromskop' (Item 146). They employ the three-colour principle demonstrated by Clerk Maxwell in 1861.
Three stereoscopic b/w images each 50 x 50 mm on glass making one stereoscopic colour image.
