Meta data: photography is one of the oldest but the coolest profession in the world. However, underwater photography is still unknown to many. It involves taking pictures underwater, which requires a great deal of knowledge of swimming to pull off. In this article, you will learn all the essential details of underwater photography.
When you take photographs when you are underwater such as rivers, the ocean, the act is called underwater photography. Often, these photos are taken when most people are scuba diving. However, the action may be done during diving on the surface, swimming, or from an operated underwater vehicle.
Furthermore, you may use an automatic camera or lower cameras from the surface into the water to take pictures. Underwater photography is essential for keeping records of data from the aquatic world. Several underwater images help keep data on Marine life and the checking of shipwrecks.
It also helps marine biology students learn the underwater landscape, cave systems, and essential geological features deep in the water. To complete the process of underwater photography, you need specialized equipment. Also, it would help if you learned the right techniques for underwater photography.
The major drawback has experienced by underwater photographers is the deprivation of color, and contrast, and sufficient light. From experience, a deep part of the ocean has little or no light penetration from the sun. The loss of color increases as you move through the water both vertically and horizontally.
To solve this problem of loss of color and contrast, underwater photographers mix two techniques. Firstly, they move the camera as close as possible to the subject. Using this technique eliminates loss of color horizontally.
Plenty of underwater photographers believe that distance farther than one meter is wrong. Secondly, the use of flash to bring back color through the loss of depth is the second technique. When utilized, Fill-flash helps restore missing color by providing full-spectrum visible light to the entire exposure.
Essential equipment for underwater photography
There are cameras designed for underwater use. For example, a waterproof digital camera works entirely underwater. The first type of camera for underwater photography was the Calypso brought back under Nikonos’s name back in 1963.
Nikonos range of cameras was created for underwater use. The Nikonos series of cameras stopped coming in 2001 as a result of a decline in demands. Cameras designed for dry work can be perfect for underwater too.
However, they must be protected by add-on housings. Housings are created for point and shoot cameras and compact cameras. Most housings are particular to the camera. They are made of relatively cheap materials.
The function of housings is to shield expensive aluminum. Housings provide flexibility. It enables users to select housings that suits their needs and utilize any lens they want.
Underwater photographers often utilize wide-angle lenses that enable close focus and shorter distance to the photographic object. Hence, the loss of clarity is eliminated. A digital camera is used more than because it uses digital media, which holds more shots than a standard film.
Hence, the decline of the film underwater similar to the way it has declined on land too. Underwater housings come with control buttons capable of reaching the camera inside. Hence, most functions of the camera are used.
Housings include connectors, which makes it possible to add flash units. Therefore, you can use a flash on the camera.
Underwater photography is now more essential than before. The reason is that it has many scientific potentials. For example, many underwater pictures provide information about water bodies, caves, plants, and aquatic animals useful for scientific research.
