Five Features That Every Underwater Digital Camera Should Have

Housing

Underwater digital cameras almost exclusively have housing to keep the technological parts from getting wet and destroyed. These housings can be made of inexpensive plastic to higher priced aluminum casing. Housing offer many options for the user, since they can choose the housing specific for their every day land camera. They can also use any lens in their collection for their photography. Housings will also have watertight ‘o-rings’ at all points where materials meet to keep water out of the housing and the camera. Underwater housings are outfitted with control knobs that access the camera inside and give the photographer the normal camera functions.

Increased Memory

Digital cameras give the photographer an added advantage over simple film cameras. Digital allows for many more pictures to be taken in a session. Since there is no film to change (nor could you change film underwater anyway), you can take many more photos with your underwater digital camera than you could with an underwater film camera. Your digital camera can also be outfitted with increased memory cards as high as 8 and 16 gigabytes. Most digital cameras will have options where you can plug more than one memory card into the camera as well.

Flash System

Since typical flash on a camera will not be strong enough to penetrate the refraction of the water, many housing units will have a separate flash system that is outside of the underwater digital camera. This flash system will be found outside the camera and housing itself and be connected via fiber optic cable. Flash should not be used as the primary source of light. Flash should serve as a supplement. However, there are situations where flash is your only option. With these situations a strobe can be used to serve in a way that you can correct and re-correct your photos as you take them.

Fish Eye Lens

Using most lenses is likely to distort the image you are trying to take photographs with an underwater digital camera. One of the best ways to limit the amount of distortion due to refraction is to use a fish eye lens. In above water photography, a fish eye lens will make a photograph appear as if you are looking at it from the view of a corner mirror in a convenience store. However, when you put this lens into the water, the refraction effect will turn the photo from that of the mirror into a typical photograph.

Macro Lens

The problem of refraction is not a problem when using macro lenses. In fact, the increase of refraction actually helps the macro lens pick up more of the image one is trying to take pictures of. This is a benefit to photographers who are trying to take photos of very small subjects. With the macro lens, especially with wide angles, photographers can eliminate the need to have excessive water between the camera and the subject. Macro lens offers close focus which can be very helpful.

Underwater Digital Cameras – What Are the Best Features?

Tony — Sun, 01 Nov 2009 17:17:19 +0000

Your skill as a photographer will take a step forward if you chose to go beneath the waves and explore using an underwater digital camera. We've all seen pictures of the stark beauty found in the sea and in other areas where the clear water opens a whole new world to taking photographs. The reality is that it is very doable and you will use the same photography skills that you use on dry land with some adjustment for the clarity of the water.

Underwater photography has changed significantly over the last two decades due primarily to advances in technology. In the nineties we saw cameras hit the market that had water resistant lenses followed by waterproof cameras that allowed the amateur photographer to shoot undersea marine life. By the year 2000 we saw a quantum shift in the paradigm of photography when everthing started to go digital.

What did this mean? It meant that the hobby photographer could take pictures (and sometimes really good pictures), get an immediate result, an not be tied to film development and waiting for the outcome. Part of the fun of using the latest underwater digital cameras is that the operational programming is so good for the new advance features that it makes the cameras easy to use and to get great results. Features such as long battery life, enhanced flash photography, automatically adjustable f-stop and exposure times make using them a breeze.

Underwater photography is now a singular segment warranting its own special techniques, equipment and group of professionals. Apart from naturalists and botanists studying underwater plant species and animal-life, even historians studying wrecks and anthropologists studying life-forms and people giving birth underwater etc are groups that have interest in underwater snapshots besides of course, scientists and biologists who photograph and study marine life.

To make sure your underwater photographs turn out well, remember these things:

Chose a basic digital camera that is designed to used underwater. Don't cover your dry land digital camera with plastic and expect it to perform underwater. Underwater cameras come equipped with special parts that prevent it from getting damaged even when submerged in murky waters and still manage to give good shots in limited natural light, depending on their quality.

Follow the operation manual of the camera for the best results. Don't be one of those that avoids the manual and them complains about how poorly the camera performed (because you didn't know what you are doing).

Always remember that the deeper you go into the waters, the poorer light conditions you will have to face, so learn the techniques of underwater photography as best as you can to be able to use white (natural) light or some type of artificial ones to counter this issue.

You can avoid using zoom feature when taking shots underwater and turn off flash wherever possible so the quality of photos is higher and not blurry, which is what it tends to be when flash is used underwater. Always study the warranty information before you put your camera in potentially damaging conditions. The warranty will spell out the conditions for use and for claims against the manufacturer.

If you have the opportunity it is a good idea to submerge the camera at the store where it was purchased to check for leaks. This way you can avoid going on that special trip and finding out that your camera doesn't work.
