How to use camera white balance

When it comes to TV photography, white balance must be mentioned. The reason is very simple. If there is a problem with this part, there will be problems with the color of the picture taken. White balance is a setting necessary for adjusting the color reproduction of photography equipment using "CCD" (CMOS) photoelectric equipment. It should be noted here that the scope of the concept of white balance is only "photography equipment using "CCD" (CMOS) photoelectric equipment." "Film cameras" that shoot movies do not have the concept of white balance. Generally, cameras have three ways to adjust white balance: "manual", "manufacturer preset", and "automatic test setting". 1. The manufacturer's preset white balance means that the manufacturer presets the white balance values ????in the machine under the two light environments of "sunlight and shadow". When you use it, you can directly research the white balance index according to the light conditions. Some machines also have a way to change the white balance every 100 color temperature values. For example: broadcast-level DVCPRO, DVW series, business-level EX1R series 2. Automatic setting means the camera detects the environment and sets the white balance value. 3. Manual setting has the photographer specify a white color, usually a piece of white paper. Let the machine take a picture of this white color and identify it as white. Generally, manual setting is the most accurate, while automatic setting is inaccurate but easy to use.
