How should the underwater camera shoot during operation?

Use a dedicated muddy water underwater camera or muddy water camera aid

This kind of camera or device is to install a pressure-resistant or non-pressure-resistant camera cover in front of the camera lens, and the medium in the closed cavity in the underwater salvage cover is air or clean water. In this way, the path of light in the muddy water is shortened during the transmission process from the subject to the lens, thereby reducing the scattering effect of the water and improving the clarity of the image. However, due to the limited length of this camera hood, the improvement is only noticeable when shooting at a closer distance.

1. Decide on the water with high transparency or when to shoot

The underwater operating waters cannot be freely chosen by the operator, but in some cases, it is normal. For example, when there are waters with high transparency and high memory quality requirements, if conditions permit, you can transfer the work object to waters with good water quality for shooting. In addition, even in the same water area, the transparency of the water will change with changes in tides, currents, weather, etc. As long as the operators pay attention to the investigation, accumulate lessons, and decide on opportunities with relatively high transparency to perform their homework, the shooting results will be improved.

2. Underwater lighting adopts oblique side light instead of smooth light

The different reflection directions of the light source have a certain influence on the clarity of the image. When the reflection direction of the light source and the shooting direction of the lens is in the same direction, under the same shooting conditions. The particles in the water in front of the lens have a greater impact on the clarity of the memory; when the direction of the light source and the shooting direction of the lens is at an angle of 30 to 60 degrees, the clarity of the image will be better. Therefore, when underwater lighting, the lighting should be kept a certain distance away from the camera to form oblique side lighting.

3. Close-up shots

Under the same shooting conditions, the closer the underwater camera is to the subject, the less light is scattered by the water during the transmission process in the water, and the clearer the image will be. Therefore, in underwater camera operation, as long as the shooting requirements can be met, the closer the shooting distance, the better.
