Art Of Autumn
Nature's way of saying stop and look at the "me" the leaves. This is my favorite time of the year. I love photographing in the fall amongst all the splendor of color available. do you ever wonder how /why the leaves turn in autumn. Here's what the experts say.The changing of leaf color in temperate forests involves several causes and reactions, but the dominant factors are sunlight and heat. Since temperatures tend to drop sooner and sunlight fades faster at higher latitudes, the progression of fall color changes tends to move from north to south across North America from mid-September through mid-November. In late summer and autumn, tree and plant leaves produce less chlorophyll, the green pigment that harvests sunlight for plants to convert water and carbon dioxide into sugars. The subsidence of chlorophyll allows other chemical compounds in the leavesâ€â€particularly carotenoids and flavonoidsâ€â€to emerge from the green shadow of summer. These compounds do not decay as fast as chlorophyll, so they shine through in yellows, oranges, and reds as the green fades. Another set of chemicals, anthocyanins, are associated with the storage of sugars and give the leaves of some species deep purple and red hues. As explained by the U.S. Forest Service, certain species of trees produce certain colors
