Underwater digital cameras also have built in features for color correction filters and flash diffusers and they are also equipped with complete storage and image editing software. This adds to the sophistication of the camera and also makes them easy to manipulate as per the situation.
The ones available today are completely high tech and are used not only for personal reasons but also for exploring, monitoring swim areas, and fishing and also for documenting shipwrecks. Today, we also have offshore trolling cameras. These have been designed specially for the videographers and fishermen.
Underwater photography has its own limitations in terms of the conditions the photographer has to face. But the true skill of the photographer solely remains in his/her ability to overcome these problems and shoot his/her best frame ever.
When you dive into the ocean, ensure you do it sans your camera. Diving with your camera will easily flood the camera with water. Therefore always procure or pass the equipment (once you are in the water) to another person on the boat.
Do not drag your equipment once you are in the deep waters. This may cause damage to the marine life.
Use an upward angle of the camera to obtain dramatic results.
Be constantly aware of all the dive gear that may float before your lens.
Ensure you use the empty space for text or graphics that can be added on, later.
The best time to take the plunge is around midday. The sun being overhead would illuminate the subjects underwater.
