Yes, you can take pictures underwater with your current camera, or purchase a separate camera specifically designed for taking underwater photographs.
At mystoretosave we stock a number of cameras designed specifically for use underwater, and most of them are relatively easy to use.
If I want to use a “regular” camera underwater, what do I need?
If you want to use a regular camera underwater, you need to purchase an underwater housing. These housings are available in a number of configurations, depending on the type of camera you own, and how deep you plan to dive.
For a pretty picture:
1. Remember that everything is magnified underwater, so distances will appear differently. Your camera will only be able to focus at certain distances.
2. Get close to what you want to shoot. Underwater, light is filtered so that all that is able to make it through is blue, and though you might be able to pick up enough light to see, your camera may not. You're going to have to get pretty close or your pictures will end up dark blue and washed out.
3. Keep your distance. This is especially an issue if you use an external flash. The perfect distance for taking pictures is approximately 4–6 feet (1.2–1.8 m), or closer if you have a macro lens. This may seem close, but most fish won't run from you if you approach slowly.
Maintain your camera.
• Most importantly, wash the outer housing after every use in salt or fresh water.
• Never ever open the housing while you are wet or dripping, or in a humid environment.
• Use desiccants inside your camera to keep the camera dry, and the lens free of fog.
