Underwater photography blends technique, patience and creativity to capture the magic of the deep. Light behaves differently below the surface — reds fade first, so strobes or red filters restore natural color. Buoyancy control matters more than any camera setting: a steady diver gets the sharp shot. Approach marine life slowly, shoot upward toward the light, and get close to your subject. Learn how to choose the right setup for your level, master composition underwater, and bring home images that tell the story of every dive.
