No.16 Tirailleurs Tonkinois (Lintap) circa 1885
This photograph, showing indigenous Indochinese infantrymen is number 16 in a series that was taken by one Dr Hocquard who was a medical officer stationed in French Indochina in the late 19th century. It was first published in Paris in 1886 as part of a series of works in “Le Tonkin, Vues Photographiques Prises Par Mr le Dr Hocquard, Médecin-Major” which was edited by Henri Cremnitz.

It is a Woodburytype (French: Photoglyptie) print which is a photo-mechanical process developed by Walter B. Woodbury in 1864. The process produces continuous tone images in slight relief. A chromated gelatin film is exposed under a photographic negative, which hardens in proportion to the amount of light. This is then developed in hot water to soften and remove all the unexposed gelatin, then dried. The remaining relief is pressed into a sheet of lead using a press that exerts 5000 psi resulting in an intaglio plate which is used as a mold and is filled with pigmented gelatin. The gelatin layer is then pressed onto a paper support.

The series of images that comprise “Le Tonkin, Vues Photographiques Prises Par Mr le Dr Hocquard, Médecin-Major” is held by the French national military museum, the Musée de l’Armée in Paris.
