One of the creators of TV images, also known as "illuminator", uses various professional lamps to create various "light and shadow effects" according to the artistic styles of different images. No matter whether it is a movie or a TV series, in addition to the dark parts, there are also bright parts and dark parts in a picture. Clever composition with light and shade is a very important means of expression in image art creation. The work of lighting engineers is synchronized with that of photographers, especially indoors, such as news, special topics, audio-visual education, literary evenings, sports competitions and other programs.
