If Atget's boat had come from Ikea, it would have sunken long before he got a chance to photograph it, with all the paper-thin veneer soaked off, and the cheap particle board core dissolved into damp sawdust down in the muck. Thank goodness, there were no Ikea stores back then.
Atget was a master in how he used trees to complement his compositions. The Post 283 example is indeed unusual. But I "got it" long ago. It is his own intuitive venture into Constructivism, for lack of a better term. Carleton Watkins and Sheeler were the photographic masters of that (only certain Watkins ULF prints clearly exhibit it, taken well before there was a school of painters doing it; Sheeler both photographed and painted). It's a daring division of space right in front of the rest of the picture, so can be intimidating in that respect; a bold experiment, at least, but certainly not the manner Atget typically handled trees.
Watkins' examples were truly prescient of modern art; but this one example of the same kind of compositional strategy with Atget might or might not have been inspired by what contemporary painters were already doing. More recently, Friedlander attempted those kinds of arboreal overlays, but in a half-baked way in my opinion - just too conspicuously forced and artsty.
It's surprisingly difficult to compose well in that manner. I was out yesterday with the 4x5 and a long lens working with a very intricate tree overlaid upon another kind of tree, but that was all at a distance and essentially two-dimensional, and in color as well - whole different ballgame.
