Falls At Little Branch Creek, Swain County, NC - 2013

Now that the forests are "greened up", waterfall photography is much more appealing. Although you can get some interesting shots in the winter, especially if there is ice around the falls, I think green foliage makes a prettier photo. A full forest canopy also gives you more even lighting (usually). Avoiding "hot spots" on the fall can be a real headache in bright sunlight, and the open shade provided by a full canopy helps with that problem. Of course, the best lighting can be found just after sunrise. You'll get better light, and less chance of turistas wandering into your photo.
