Until recently, an underwater camera were mainly Oceanology, but with the advent of digital cameras and such a wonderful sport such as diving, the situation has changed radically.
The fact that the capabilities of most cameras, previously used for an underwater camera were very limited.
Plus they are pretty expensive cost, so let them not everyone could afford.
By contrast, modern digital cameras do not impose virtually no restrictions, and thus have a relatively low cost, and its technical characteristics in a little inferior than even the most expensive film cameras.
To remove the water can be made via the so-called amphibious cameras or any other camera designed for underwater photography and protected akvaskopom, soft box or a hard cover.
Cameras amphibians.
Cameras amphibians – a digital or film cameras, the main feature of which is immersion in water at a shallow depth and short duration (usually no more than an hour).
As an example of such a camera can cause Pentax Optio W20.
C using the Pentax Optio W20 can be removed without any problems fish and coral reefs, and scuba divers, floating in deep water.
Akvaskop is a box of glass located at the bottom, and a small hole for the eyes, which is located at the top.
The easiest akvaskop can easily make yourself.
To do this, wrap the camera usually very thin plastic bag, and then push the edges between the rubber trim and glass masks so that they are very tightly clamped between them.
With the help of a camera, protected akvaskopom, you can lay directly on the mattress, remove coral reefs, crabs, sea urchins, and so
But in doing so, it must be remembered that the lower akvaskop – very sloppy design so completely omit it in the water can not.
Softbox – these are special cases that protect the camera while underwater photography.
They are made of soft plastic and have a glass window for the lens.
It is worth noting that the most popular in our country enjoy softbox company «Ewamarine».
Before diving into the water softbox should be mandatory fob.
Otherwise, already at a shallow depth, he will squeeze, because of what the camera control buttons will be pressed down, and its lens is pressed into the housing.
The main advantage of soft box is their relatively low cost.
For example, soft plastic cover to flip digital camera worth about two hundred dollars, and for a simple digital “soap dish – 50.
Disadvantages softbox is the fact that it must be constantly washed and thoroughly dried, and periodically lubricate its clamping screws.
In addition, the inflated bag of soft plastics greatly hinders immersion in water, and at great depth, he gains weight and starts to pull down.
Hard covers.
At the moment, hard covers, which protect the camera during an underwater camera, producing and manufacturers of cameras, and third-party manufacturers.
In this hard-covers are available for both SLR digital cameras, and digital “compact digital cameras.
Do the same to any polycarbonate, or metal, although metal, hard covers and begin to gradually retreat into the past.
In most cases, hard cases are produced by some specific model camera.
True, there are exceptions.
For example, the company «Ikelite» produces several varieties of hard covers, which are ideally suited to the mirror digital cameras from various manufacturers.
But such cases are usually much more expensive.
The main advantages of solid covers can make them permanent buoyancy, due to which greatly simplified the movement of a diver, as well as additional magnifying glass for a viewfinder.
The only drawback is their considered a very high cost.
