How the muddy water penetration camera works

Just like the eyes are covered with a layer of fog, the turbid underwater camera is equivalent to a lens that can restore the foggy underwater world to a clear underwater world. Underwater camera (underwater movie camera) is an underwater camera system composed of high-quality cables as video transmission control lines, plus control boxes, pay-off winches and other auxiliary control equipment. Mainly used in petroleum, deep water exploration, underwater operations, marine fisheries and other underwater fields. The main problem faced by underwater photographers is the loss of color and contrast in their subjects. Longer wavelengths of sunlight (such as red or orange) are quickly absorbed by the surrounding moisture, so they appear blue-green even to the naked eye. The degree of color loss is related to the vertical and horizontal passage of light, so colorlessness and blur appear even when viewed from a distance from the camera. This effect occurs in apparently clear water, such as that surrounding tropical coral reefs. Underwater photographers solve this problem by combining two techniques. The first is to get the camera as close to the subject as possible to minimize horizontal color loss.
