This image was taken at Niagara Falls during their light show which they do every night. It's quite an amazing thing to witness and if you have the chance the go I highly recommend it. The coloring in this image was all natural meaning it's what I saw, not enhanced in photoshop. The hardest part was getting a shot without falling over the edge!
Camera settings: Nikon D800, 3 sec at f/4.0, 26mm at ISO 50, flash did not fire. Taken at 8:46pm on August 30, 2012 by Jason Lanier.
