Underwater shooting skills of sports camera to avoid blurring when shooting underwater.

1. Keep the camera still. Good buoyancy control is very important in underwater photography! Less camera movement means that you can use a slower shutter speed and let more light reach the camera sensor. If you use an underwater action camera such as a waterproof small camera to shoot in low light, and you are using the camera automatic exposure setting, the camera will use a wide aperture to compensate for the low light, higher ISO and longer exposure time. If you are shaking and trying to stay in one place, you will eventually get a blurred shot.

2. Don't mix sand and silt at the bottom. Nothing can destroy the clarity of water as quickly as a diver touches the bottom with his fin. Sand and silt can easily form thick turbid water clouds, which makes focusing very difficult. The autofocus system on a digital camera will search the contrast area-low brightness underwater is a challenge for many autofocus systems, but turbid water will further reduce the contrast and make it almost impossible to focus. Once again, controlling your underwater movement steadily is one of the most important factors to take clear underwater photos.

3. Be close to your topic. On land, if you can't see the peaks or buildings a mile away, you know that there is a serious problem with the air quality that day. Although underwater, even under perfect conditions, visibility will be greatly reduced, whether it is because of the density of water to prevent light from spreading to far places or because of tiny suspended particles in water. Similarly, buildings become more and more clear in smoky days. The closer you get to them, the clearer the underwater objects become. If you shoot a small object underwater, you will want to capture as many details as possible and make sure that you can focus accurately.
