Day 39/365, originally uploaded by mssphotos.

This shot was little hard to capture. I took the refuge on a big rock to avoid the moist from the falls falling right on my camera. I used the sigma wide angle lens with ISO 100, 14mm, f/11 at 1/20 sec. I thought the moist spoiled the shot but this is what I got having the moist coming from the left side where the falls was.
