1. video camera (different models and lenses are selected according to the budget of the customers making promotional videos, and of course the shooting effect is different). 2.

Using the hood can reduce the light spots produced on the CCD image sensor after the light is refracted by the lens, which can better represent the shooting subject and reduce the interference of stray light on the subject, so that the picture taken at night is relatively pure. 5. Adjustment of white balance (CCD, the photosensitive element of the camera, can't automatically correct the change of light like human eyes, so we should pay attention to the adjustment of white balance. Choosing different white balance will directly affect the tone of the film and the artistic conception expressed. Generally speaking, don't choose automatic white balance, which will affect the inherent color of the light and make it lose its unique color temperature feeling. It is a better solution to adjust the white balance by using a school chromatogram.
