Shoot Close

Water is about 800 times denser than air. As camera-to-subject distance increases, the sharpness and the color of your subject decrease. For natural light pictures of reefs and divers, a wide-angle lens lets you get up-close and personal with your subject. For optimum results, use a 12-mm, 13-mm, 18-mm or 15-mm lens. The wider the lens (a 12-mm lens is wider than a 15-mm lens), the closer you can get to your subject.
