What should I pay attention to in underwater photography? What problems should be paid attention to in underwater photography?

1. Keep the photographic equipment dry to prevent water from entering.

For underwater photography, you can choose a professional underwater camera or a digital camera with a waterproof shell. When using the waterproof shell of digital camera, it is necessary to carefully check whether there is leakage before launching.

2. Wear the smallest mask to take a picture.

Most underwater photos are taken close to the subject. The main problem encountered by the camera when shooting underwater is that the mask will separate the eyes from the camera viewfinder, resulting in parallax problem. It is recommended to wear the smallest mask and keep your eyes as close as possible to the camera viewfinder.

3. Choose the diving site according to the theme.

The water channel and waterway around the island are the best diving places to shoot sharks, octopus, whitebait and other big fish, but the airflow in the water channel is usually strong, so it is necessary to grab something to keep it stable. If you want to photograph all kinds of beautiful tropical fish and corals, it is the best place to hide in shallow water.

4. Due to the particularity of underwater shooting, attention should be paid to the use of light.

There are a lot of suspended solids in seawater, which reduces visibility. The best shooting distance for underwater shooting is 1/4 of the maximum visible distance. When shooting underwater, the sea water seems to have a light blue filter for the camera to prevent red light from shining. The use of color film often leads to the blue color of color photos, and the skin color is more affected by it. When shooting in shallow water, when using warm color filter, we must pay attention to the water layer between the subject and the camera, and pay attention to the accuracy of focusing.

In order to achieve a larger underwater shooting angle, you can choose to shoot a little farther from the land when shooting underwater, so the red filter is improved. When the environment is dark, the flash is generally used as an auxiliary light source. In addition to macro shooting, external flash is generally used, and the use of built-in flash will make the light reflection of plankton and sand appear "splash phenomenon". When shooting at high diving depth, it should be noted that with the increase of diving depth, the light will become darker and more dispersed.
