During the shooting process, there are many factors that affect color reproduction, indoors, outdoors, early morning, dusk, daylight and frequent changes in lighting, which require the film crew to work carefully.
Basic practice:
(1) External adjustment of standard viewfinder monitor and camera The standard monitor is an indispensable reference for ensuring the correct color reproduction. Generally speaking, after a standard monitor has been checked by an oscilloscope that its waveform conforms to the standard, its external adjustment cannot be adjusted in principle, but should be kept consistent throughout the filming process.
When the hue, color saturation and brightness of the camera and other monitors and TV sets are inconsistent with it, they should be adjusted to be basically the same. During the filming process, the white balance should not be consistent. The white balance and color filter of the camera should be adjusted at any time.
(2) Measures to ensure color reproduction in the case of mixed light sources. In the case of mixed light sources, standard monitors can quickly help you decide to use color filters and determine the reference light source for white balance adjustment. Cameramen must quickly determine the scope of the subject, whether the main light source of illumination is daylight or light, panoramic view or close-up.
Generally speaking, the daylight filter is used when shooting panoramic views and there are more transparent windows; when shooting close-up and close-up, when the light is the main light source, use the light filter; the lens directly adjusts the white balance of the subject. Of course, if you have filter paper, you can add it in front of the lamp to maintain the consistency of the color temperature in the case of mixed light sources. It has a tone. When setting the tone of the program, we must not violate the need of science, intentionally or unintentionally change the tone of the subject to obey the tone of the whole film. This purely pursuit of the consistency of the tone is not advisable in corporate videos.
