It required special watertight housings to be able to be used for underwater photography. Nikon underwater camera had water get in touch with optics which permit underwater imaging possible but lacked the ability to concentrate correctly on land. Nikon was discontinued due its obsolete film system in 2001 but an amphibious range finder by the name of Motor Marine III is still being manufactured by Sea and Sea.

An is specialized gear which is obviously intended for underwater photography but it also may be used on dry land. Underwater camera have special protective camera particular housings intended for numerous digital point and shoot cameras, digital compact cameras and single lens reflex cameras. Housings are made out of a combination of Polycarbonate and Aluminum or either one of these. All of such housings are equipped with control knobs allowing photographer to carry out his job with ease. A system of Silicone O-Rings at some crucial joints tends to make the housing waterproof. Photographers use wide-angle and/or macro lenses in their underwater camera which enables them to have a close focus. This is especially useful when taking photos of sea creatures which might prove harmful inside a close range.

Whilst utilizing an underwater camera with wide-angle lens, a distortion within the image might be encountered due to refraction. Due to this cause an manufacturer utilizes dome-shaped or fish-eye ports to maximize the effectiveness of their.Distortion brought on by refraction isn't an issue with use of macro lenses in underwater cameras. As a matter of reality refraction adds to its advantages by growing its magnification permitting capturing of very small sea objects. Therefore a simple flat glass port is used.

Because of lack of sunlight exposure underwater, there are a couple of problems with an with wide-angle lens regarding use of flash lights. Usually, wide-angle pictures may be 100% strobe light in interiors of a cave or perhaps a shipwreck but these are rare circumstances. Many contemporary underwater camera producers have equipped their cameras with through-the-lens (TTL) metering for the purpose. While using underwater camera with macro lens, 100% strobe light for exposure is extremely likely to become used by photographers due to unavailability of sufficient sunlight and proximity using the subject. Whatever type of an, housings, capturing method and relative gear may be utilized for underwater imaging, there is no doubt that we could by no means have had seen the fantastic globe up-close if such gear wouldn't have been invented.
