There are some basic elements that are required for green screen cutout, such as the materials used, the location of people and objects, and the lighting in the foreground and foreground, which are very important for green screen cutouts. In order to make the process of cutout simple, the green screen background needs to be completely lit, because the shadow is difficult to cut. Background light around hair or transparent objects such as glass and liquids is the most basic.
