The reason why professional cameras are all black

A camera, referred to as a camera for short, is a device that uses the principle of optical imaging to form an image and records the image with a negative. Many recordable imaging devices have the characteristics of cameras. Medical imaging equipment, astronomical observation equipment, etc. A camera is an optical device used for photography. The light reflected by the camera is focused by the camera lens (camera lens) and the shutter that controls the exposure. The photosensitive material injected by the camera into the black box constitutes a potential pixel, which is developed and fixed to form a permanent image. This technique is called photography. Professional cameras are all black. At the beginning of the camera with metal body, electroplating technology was not mature, so almost all cameras at that time adopted dark technology. Later, the level of electroplating technology gradually improved, which solved the cost problem of electroplating, and the camera gradually transformed into a chrome-plated body. Although many people like the pattern on the plated alloy fuselage, professional photographers who report on battlefield photography don't like it, because the bright fuselage is easy to be found by the enemy and easily become the target of attack. In other words, the black body is specially made for professional photographers, so many enthusiasts are also looking forward to the black body. The black body that used to be a special camera has gradually evolved into an ordinary camera. The change took place in the first half of the 1980s. At that time, the SLR camera with plastic body came out. Camera manufacturers have a new understanding of chromium plating process, because the electroplated outer layer is easy to fall off, and solving this problem will increase the production cost. The treatment solution used for electroplating materials also pollutes the environment. Despite these problems, professional photographers and fans have always had a soft spot for boldface. In this context, the black body naturally becomes the mainstream model.
