Combing through hundreds of autumnal photos today, I was struck by a few that evoked a sense of forest textures and layers. In each case, it was the light that helped define the depth and shape of the image. I’ve been struggling to put this concept into words, and it’s really best explained by just taking a good long look at the images. But basically it means that, as I was taking the photos, the light was the main factor in determining the composition of each frame instead of a dominant foreground subject. I love the way the sun plays around the edges of the trees, still bright in the late afternoon, but softened by the time of year (early September). Ttwo are iPhone shots, one is not; can you tell which is which?
