Photogravure and photomontage

While I was reading a guide of Indochina published by the Touring Club of France (this one is the 1910 version hold by the Library of Congress while the one I read is a longer version -published in 1911? - from the Bibliothèque nationale de France), I was struck by the photos used to illustrate the text in photomontage style. Some looks really uncanny, with a collage of a French woman on the photo of exotic site. Like this one,

There is mention of F. Bouché as the 'photograveur'. I then wrote to my colleague in the States who is specialist of artistic techniques in the 19th century, Rachel Skokowski.

She explained that 'photogravure' is a 19th-century photography technique that combines photography with etching (you basically transfer a photograph onto a metal plate that is then printed). The photograveur would be the person who made the prints, and is probably a different person from the one who took the original photos.

She also gives me useful links to read further:

I then discovered André Disdéri's 'carte mosaïque'. They are quite charming, and the Commune's one intrigues me. It is really upsetting to think about how many young people were killed during this event.

Guide aux ruines d'Angkor by J. Commaille

Published in 1912 by Gallimard  (but it might have been published earlier and the Gallica copy could be a re-editio). One of the early guidebooks for tourists of Angkor.

This guide is quoted with photos by another guidebook 'L'Indo-chine' published by the Touring-Club de France, comité de tourisme colonial in 1911 (date given in Gallica). This edition is bilingual and is part of the development of tourism in the region [to be linked with the establishment of the 'Angkor Park' by the EFEO in the same period]. This guide gives practical information as well as description of sites and monuments tourists could visit (transport, accommodation, travel time).

These guides are to be put in contrast with the exotic novel by Pierre Loti, Le Pèlerin d'Angkor published in 1912. This travelogue gives a different image of a trip to Angkor: mysterious, dangerous, difficult to accessible, in contrast to a well-organised trip by tourist companies.

Another guide which seems to be well known is Guides Madrolle. This advert I found at the end of La Dépêche coloniale illustrée, a special edition of 1918 on the Travailleurs indochinois.
N.B. In this volume, there is an excerpt of J. Boissière about the character of the Annamites (To read).

Jardin Colonial at Nogent sur Marne

Map of the Colonial Exhibition in 1907

I read an article published by La Dépêche coloniale of the 3 Juin 1909 about the Jardin colonial in Nogent sur Marne, in the east suburb of Paris. This 'Agronomical Garden' was founded in 1899, it hosted a Colonial Exhibition in 1907. The Marie de Paris (Paris Municipal) acquired it in 2003 and is now renovating the pavilions. The newspaper Le Parisien covered the story here http://www.leparisien.fr/paris-75/paris-un-pavillon-colonial-restaure-au-jardin-tropical-du-bois-de-vincennes-16-08-2019-8134371.php

1864: Foundation of the Jardin botanique et zoologique in Saigon preceded this foundation of the administrative organ in the métropole 

1902 : Foundation of the École nationale supérieure d’agriculture coloniale as an integral part of the Jardin colonial (this is to be linked to the article on 'La Ville de Saigon' in Revue indochinoise illustrée in 1893 recently read that gives details about the Botanical Gardin in Saigon including the administrative staff in charge of developing seeds and plants)

'La Ville de Saigon' in Revue indochinoise illustrée in 1893

Economic expansion is to be supported by research in new plants in the colonies. I am also thinking about the foundation of the EFEO in 1899 in Indochina. Efforts were made from different parties (not always concerted) to create and master knowledge about Indochina
