What is the most important role of color in the performance of picture modeling?

1, highlighting and expressing the role of the subject.

Because human vision is the most direct and sensitive to color, some photographers make full use of the characteristics of color in the artistic creation of color photography, and consciously arrange those colors that can arouse the audience's interest near the subject in the picture to contrast and highlight the subject and guide the audience's attention to the subject.

2, the role of rendering and contrast theme

In color photography. Using color to render and contrast the theme has a unique function, so some experienced photographers always regard the choice and arrangement of color as an important means of artistic modeling.

Therefore, when using color to render and contrast the theme, the following methods are usually adopted: First, the color atmosphere of the picture of color photography works is created by using the color temperature difference between photosensitive materials and light sources. For example, the sunrise and sunset scene with a color temperature of about 1850K is shot with sunlight color sensitive film with a color temperature of about 5600K, and no color temperature correction filter is added when shooting.

Make the picture show a natural orange tone to emphasize and render the warm tone atmosphere of the picture. The second is to use the color cast of the color filter on the color sensitive film to create the color cast phenomenon of the picture, thus enhancing the color nitrogen of the photographic picture. For example, when shooting a thunderstorm night, in order to render the atmosphere, when shooting with light film, you can add a blue filter to the light that outlines the light; The third is to use the color-cast characteristics of color photographic film emulsion to make the picture color cast and render the picture atmosphere.
