Underwater Photography Explained

The art of underwater photography takes into account a lot of things like equipments, techniques etc. Present technology has greatly changed our observation of underwater photography. Cameras are much easier to use and lodging manufacturer have given us a sometimes baffling array of options. While this guide emphasize exclusively on technologies of underwater photography, but the fundamentals remain the same which applies to normal photography.

Finding the right theme, capturing the right moment, presenting it in the right fashion is what makes the underwater photography challenging. The new equipment and techniques makes it a little easier, and a little more reachable. The principal hindrance faced by underwater photographers is the intense loss of color and contrast when sunken to any significant depth.

The larger wavelengths of sunlight (such as red or orange) are engrossed quickly by the surrounding water, so even to the naked eye everything appears blue-green in color. The loss of color increases both vertically and horizontally through the water column, therefore subjects away from the camera will also appear colorless and imprecise. This effect is true even in actually clear water, such as that found around tropical coral reefs.

Given that underwater photography is often done while scuba diving, so it is important that the diver be adequately skilled so that it remains a rationally safe activity. Good technique used in scuba diving has an impact on the superiority of images and pictures, since aquatic life is less likely to be petrified by a calm diver, and the atmosphere under the water is less likely to be dented or disturbed. There is the risk of encountering poor circumstances, such as grave currents, tidal flow, or poor visibility. And usually underwater photographers try to avoid these situations whenever possible.

If you have the right equipments and gears to get into the water then here are the few guidelines you should follow:

• For most images (within 3-4ft), you are required to turn the flash on and set it to the mode of forced flash rather than auto flash as it will help to add color to the images you shots, or else they will look blue. And further from 3 ft turn off the flash.
• For maximum time macro mode is required. So it is necessary to learn to turn macro mode on and off and also know the range of the macro mode.
• At times, keep your camera at the widest setting. As it affects how strongly you can focus, in macro mode. And if you zoom in, it gets difficult to focus closely the matter, and which in turn defeat the function of macro mode.
• External strobe is the best way to improve the quality of images. To use the strobe, you are required to master the technique of controlling the camera's aperture, and control the power of the strobe.

Underwater equipments

There exist numerous utilizable alternatives for underwater photography, like digital point and shoot cameras, compact digital cameras with complete revelation controls, and SLRs (single lens reflex cameras). Contrasting the earlier amphibious or waterproof camera, the first was the Calypso, launched again as the Nikonos in 1963, which is designed exclusively for underwater usage; these cameras now entail housing for underwater use. Nikon discontinued the Nikonos series in 2001 and, as it is a 35mm film system, it is somewhat superseded, but some photographers still choose this approach.

There are optical issues with using cameras inside a waterproof housing. Because of refraction, the image coming through the glass port will be vague, in exacting while using wide-angle lenses. The resolution is to use a dome-shaped or fish-eye port, which corrects this deformation. There are also issues with some digital cameras which do not have satisfactorily wide lenses built into the camera. Some housing also permits for the use of wet-coupled lenses, which thread on to the external of the lens port and amplify the field of view. These wet-coupled lenses may be added or removed underwater, allowing for both macro and wide angle photography on the same dive.

Thus with the use of right techniques and right equipments the underwater photography can be very successful. For those who share the passions for the world cherishing under the surface of water and photography must follow the instructions described above for yielding the overwhelming results.
