CYANOTYPE is a monochrome development technique perfected in 1842 by John Frederick William Herschel, a pioneer of photography. Thanks to a skilful chemical mixture of sunlight and water, an image with a more or less dark Prussian blue tint is revealed on paper: the result is a cyanotype. The addition of a tannic solution produces sepia colors with varying degrees of contrast.

STEREOSCOPY is a technique that reproduces the perception of relief from two images: it’s the ancestor of 3D. Using a camera with two separate lenses, we can capture two twin images side by side, separated by just a few centimetres (the same distance as between the pupils). First introduced in 1849, the Vérascope was marketed to the public by Jules Richard in 1893. This device was capable of photographing the souvenirs of the peregrinations of a new, wealthy clientele on glass plates: stereoscopic lenses were thus obtained.
The stereoscopic view you’re holding in your hands comes from Colonel Evariste Lasne-Rochelle, born in 1861. An avid photographer, from 1905 he took pictures of his native Brittany and of his travels abroad until the 1930s.
I get these rare images of the Angkor temples from the early 20th century, in their «original condition»! Scanned in very high definition and reworked on the computer to get the right settings, I then made unique cyanotype prints, all handmade.
