What is the principle of turbid underwater camera?
Underwater film camera is an underwater camera system which uses high-quality cable as video transmission control line, plus auxiliary control equipment such as control box and pay-off winch. Mainly used in oil, deep water exploration, underwater operation, marine fishery and other underwater fields. The main problem that underwater photographers will face is the loss of color and contrast of the subject. Sunlight with longer wavelength (such as red or orange) is quickly absorbed by the surrounding water, so it looks blue-green even to the naked eye. The degree of color loss is related to the vertical and horizontal penetration of light, so it is colorless and blurred from the camera. This effect occurs in clear water, such as water around tropical coral reefs. Underwater photographers solved this problem by combining two technologies. The first is to keep the camera as close as possible to the subject and minimize the horizontal color shift.
