Underwater Photography Tips
Though using digicams for underwater photography is comparatively simple, there are important differences between what is required to shoot underwater vs on land. Most prominent is the lighting compensation required in the sea depths.
The deeper the depth the more compensation is needed for reduced light. Artificial lighting and the manual white light balance features of an electronic camera supply the solution. All colours noted on land are obviously defined by where they fall in connection with first colours. The properties of natural underwater light are quite different. Color frequencies are so far diffused that all you are left with is blue. This serves to clarify why water appears bluish when looking up towards the sky while submerged deep in the sea. As a consequence a camera's automated white balance may not supply the mandatory precision. Non-white objects might be understood as white and corrected inappropriately. Bluish hint and little color are common when using many standard cameras for underwater photography. Using the manual white balance settings on an electronic camera can help overcome these lighting inaccuracies. The setting used will depend upon the clarity of the water. A basic axiom that may be used is : Sunlight mode for depths up to ten meters or flash aided macro shots, Clouded setting for deeper depths or when flash helped macro mode produces overpowering bluish tones.
This'll help to bring out more colourful colours with less blue. Infrequently an obvious haze appears across the whole image. This is light reflecting off sand particles and plankton, which can sometimes be rectified by employing an external flash or video light rather than an inbuilt flash. The sole exception is close-up macro shots where the camera is extremely near to the object it trying to capture. The employment of zoom settings is also significantly different in underwater photography.
Adjustments must be made to compensate for light refraction where the air in the lens meets the water.
This idea can most simply be demonstrated by putting an object half-way into a tumbler of water and observing the twisted appearance of the submerged portion of the object. If employing the same zoom setting on land as underwater, a narrower field will result so compensate appropriately. Adjustments in the position of the camera must be made when shooting wide angles underwater. The camera must be positioned at a greater distance from the object than would be needed on land to gain identical results. Underwater digital photography can simply be mastered thru basic random attempt, particularly since you do not have to pay for rolls of film. The most important thing that must definitely be remembered if your journeys are going to be a hit is to ensure that your camera is always safely enclosed in the water-resistant surrounding. Regular inspections of the surrounding can make sure that each one of your underwater journeys will be as satisfying as the last.
