Apart from doing photography I seem to find a lot of hours researching the history, philosopy, and aesthetic development of photography. For any of this to have value as genuine scholarship capable of holding up under critical review I have to "define my terms" on a consistent basis. My photographic taxonomy is a bit stilted and not the way people generally converse but it seems to work.
The way I sort out the various actors in photography is to think of them by what they do; more exactly by what exists when they leave off what they do. Other commentators, and Beaumont Newhall is a prime example, tended to call any attention getting figure associated with the consumption of photo-sensitive materials a photographer. Beaumont, all-round good guy that he was, never really understood the photographic process itself so his histories focus on personalities rather than pictures. It would be like a groupie writing the history of rock and roll. There would be plenty about the pecadillos of musicians but little on the music itself.
A "Photo-Director" like Nadar, Bert Stern in his heyday, Tracey Moffatt, or Annie Leibovitz perhaps, might be credited for a photograph without actually touching a camera in a decisive way. Sure there is a lot of organising. The sets people, lighting guys, bored talent, all have to be motivated to carry out the directors artistic vision. And the lab staff have to be given hell if the results can't be manufactured to a prestigious standard. But I cannot bring myself to call these talented figures photographers.
A "Camera Man" like Henri Cartier-Bresson makes exposures, often in the thousands, but produces nothing visible. Again there is a talent and possibly an obsession in being a relentless, implacable voyeur with a camera but surely "camera man" is the truth of it and an extension to "photographer" quite unjustified. When I look at a photograph credited to H. Cartier-Bresson I know what I think: "Gelatin-silver photograph by Pierre Gassmann (H.C-B's lab guy) from an exposure by Henri Cartier-bresson.
A "Photograph Maker" is the person who actually makes a picture out of light sensitive materials. In an ideal world it is the same person who generates the original inspiration, finds the subject matter, does the camera work and the darkroom work, and signs their personal creation - the final photograph. Perhaps the term "Photographer" should be reserved for an individual like this. And a capital "P" should be part of the title.
Unfortunately the word "photographer" has become debased by many minor and major deceits that are so pervasively common and familiar that most folks don't notice them. Some "photographers" are responsible for every dot and tittle of their work; good for them. Some "photographers" have their pictures constructed out of the creative finger prints of other people. From the point of view of formal scholarship the term photographer is best left aside.
As for me, I'll settle for photograph-maker.
