Pages and pages of WW1 photos - in colour! I knew that there some people taking colour in WW1 and I've an Australian book with a few shots of No 1 Sqdn AFC in the Middle East 1918 taken by Kingsford Smith but these are French Western Front (although there are a few Ausses in these as well). Colour is variable but some very good shots - a few vehicles too.
These photos are great, I have this link in my favorites section. I was just watching the <Military Channel> they were playing the WW1 series, it opens with some of these great photos.
I posted a site a few weeks ago which has examples of the work of French war photographers who used the Lumieres' "autochrome" technique (Paul Castelnau, Fernand Cuville, Albert Samama-Chikli, Jules Gervais-Courtellemont and Léon Gimpel).
The Australians appointed two official photographers, Hurley & Wilkins, who used a similar, British system called Paget Plates, and it was they who took photos in Palestine and Gallipoli. This site shows some of their work:
