Capturing picture underwater is always a special thing. And this is because the underwater world is totally different than ours so it always surprises us.
Underwater digital cameras are useful in many different ways. For tourists they are a welcomed gadget, enabling them to capture underwater moments. For marine scientists like marine biologists, the digital underwater camera is a very useful tool that helps them study the underwater world. And for marine photographers digital underwater camera is their best friend, as it is the key tool of their business. But my article is intended for people for whom the underwater world is just a source of enjoyment, of unforgettable memories. And just like you, I wondered how I would catch underwater memories without transforming my camera into a wreck.
And believe me that a simple waterproof camera is not going to be enough for underwater photography. This is because submerging a camera underwater is similar to throwing it on an open road and being ridden over by a lorry. Waterproof means resisting to certain levels of water pressure.
So, in this respect, I recommend you to go buy a device specially designed for underwater photography, that is, a real underwater digital camera.
You’ll not find everywhere such a device, as the majority of cameras are electronic and will not be able to resist well to water pressure and the water itself. The best option out there is a digital camera casing. It is a good enough solution to transform your standard digital camera into a true underwater digital camera.
So, if you already own such an underwater digital camera and want to start taking some pictures with it for the first time, please take into consideration the following useful aspects for having the best possible memories.
Firstly, be aware that the farther you go beneath the surface of the water, the darker the underwater picture will be than the ones taken out of the water. This is because the light diffusion makes the red spectrum to look darker. So, use the feature called white balance that is built-in your digital camera to brighten your images. Secondly, be also aware that underwater images look larger than those taken outside the water using the same camera settings. So, use the viewfinder built-in feature in order to take the best possible output.
Try to remember that it is not advisable to use underwater the built-in flash feature of digital cameras. This is because it produces the so called marine show phenomenon meaning the picture will be blurry and filled with spots resembling white particles floating above. So, use an external flash attached to your camera.
Before going underwater, test your camera for leaks through the case by submerging it for a few seconds into the water. Verify also for any hair or grain of sand that might provoke damage to the camera by preventing the case from being perfectly sealed. Try also putting some silica gel inside the casing but being careful not to affect the good functioning of the camera. Its role is to absorb moisture from inside the camera casing.
Your digital camera may permit the changing of lenses. This is a good feature because replacing the standard lenses with the macro lenses will make it easier for you to shoot pictures without being too close to your subject. You’ll avoid startling it and also possible unwanted events.
And, last but not least, it is important to wash out the salt from your digital camera casing. Salt crystallize itself possibly causing leaks. If you observe that salt already entered into the casing, wash it thoroughly with water streams.
