Benthic photography develops as digital camera and gain ground change. However, why to no matter use,plant camera and equipment, how be just a piece of good benthic photo? Though photography is very personification, beautiful, also be an individual subjective feeling. However on whole, if fruit is right anxious reach exposure accurate, illuminant and contrast are average, principal part is lively, this piece of appearance is very prominent.
After all does neuter flotage * have to photography how old influence?
(One) can stable camera, handle especially slow fast film;
(2) decrease churn the opportunity of the deposit that has seabed and sand, affect photo structure;
(3) decrease destroy coralline opportunity, also can avoid oneself to be harmed even;
(4) can help reduce air consumption. Ever witnessed because certain diver is extremely happy ground of be beside oneself films and guide to the incident that lack spirit, although was not brought to greater harm finally, dan Yike envisages the firm Bei scene at that time, besides, if processing is undeserved, the likelihood guides to tragic result.
* about neuter flotage
To placing underwater object, the size of the flotage that it gets is equal to the weight that the water that it discharges estimates. If the object in water discharges the weight that boiled water estimates to be more than the weight of object itself, the object is float on surface, we say it is had buoyancy. Sink conversely, call negative flotage. The weight that if the object discharges boiled water,estimates and object itself are equiponderant, content experiences suspension Yu Shuizhong, achieve neuter flotage.
When phreatic water, it is very important that study controls buoyancy bulk in surface and benthic. Rest in surface for example when, buoyancy can save physical strength, and when benthic, time need maintains much to make you relaxed in neuter flotage ability free land is in water roam, maintain good visibility, also can avoid to make the flimsy biology in you and water is harmed.
Diver can be passed match adjusting gear of heavy, flotage (BC) the size that will adjust buoyancy with breathing depth.
How to improve neuter flotage skill? Not difficult of course, those who want an attention is:
(One) everything by slow-motion begin, relative to air, the resistance of water is a lot of greater, slow activity is the most effective to saving energy of life, at the same time Yi Ke bring down scares to biologic degree, maintain biologic nature pattern, reach be close to biology of draw materials main body more easily, obtain optimal photography position and angle;
(2) good breath enrages control, slow and deep. Below benthic, inspiratory affect buoyancy with expiratory metropolis, bring about hold machine is not stable. Delay is slow-motion, but the bring down is begged to aerobic beard, spirit way also is controlled easily. When undertaking filming, after handling set of good watch for a chance and composition of a picture, before pressing shutter can make right amount my energy of life momently, help filmed stability;
