When you’re snapping photos in water, it is difficult to capture sharp images because you and your subject are constantly in motion. Many cameras resort to higher ISO levels to capture better images, but that can also result in image noise.
• Waterproof cameras are safe in a pool, but if you’re taking the camera to the beach, be careful of sand. Manufacturers may market their cameras as dustproof, but a single speck of sand trapped in a sealed gasket can break the seal and cause water damage.
• Never open sealed the compartments in or near the water.
• Don’t use the flash under water. Debris and particles in the water will light up like stars.
• Waterproof cameras do not float; in fact, they’ll sink like a stone. If you’re snorkeling in open water, make sure to attach a floatable wrist strap.
• A carabiner provides an inexpensive way to loop a camera on a swimsuit.
It takes a bit of practice and a little luck to get really good underwater photos ?please do not think that every shot you take is going to make the cover of SportDiver magazine.
You need strong sunshine and clear water. The middle of the day is best, when the sun is at its highest.
Best results will be just below the surface. Light disappears quickly as you go deeper, as do colours (one of the advantages of digital cameras is that you can retouch your photos afterwards to replace colours lost underwater).
Even clean water is full of microorganisms and other particles. The less water between you and your subject, the less difference this will make and therefore the clearer your shots are likely to be. Wide lens and close up is the secret.
