[1859 - 1936] French photographer, writer and theorist

There is still a misunderstanding on the subject of the straight print, as opposed to the modified print. Some champions of pure photography, as it is called, will even deny that a modified print is a photograph at all. For my part, I believe that if the X deposit forming an image is built up by the action of light, under the shadow of another image, transparent, and also due to light action, the result must be a photograph, whatever modifications the photographer has thought proper to introduce amongst the relative proportions of the deposit. - Robert Demachy
