This photo merits a special note. I used a slow shutter speed on this, in order to better capture a sense of fluidity. The result was rather over-exposed, however. What you see here includes a gamma correction of 0.3, which is why the cliff face behind the creek is so dark. I really like the sharpness of the lines in the water caused by the gamma correction, and I think it's a good example of using post-processing to get an otherwise impossible shot.
