The very first step in trying to understand green screen stages is to identify a studio that uses green screen or “chroma key” technology in its film and other productions. This is important because to understand something, it is simpler when it is physically present, visible and within the reach of whoever is making an attempt to know more. Most studios have a special room or area specifically reserved for chroma key technology aided film and video productions. There are cases where stages can be briefly set up in a room used for other reasons. In such a case, one of the walls is mostly used as the screen.

In understanding green screen stages, it is necessary to start from the fundamentals. That is, how a stage is developed from the first step to the last step. To begin with, the materials have to be acquired. This is the material that will serve as the background. This can be a card, tarpuline, or in circumstances where the wall is used as the screen, the wall. Naturally here the wall is not acquired. Instead, it can identified. The next step is painting the chosen material green. The wall, card or tarpuline is painted in the color green. It is of utmost signification that materials chosen for the stages are of top of the range, and not easily wrinkled or subject to tear. This is because the quality of green screen stages bear a direct effect on the quality of the final production, be it a picture, video or film.

It is very important to bear in mind that any material selected for a chroma key screen should be very smooth. The painting and shade on the material should be even and moderately bright. After the material has dried properly, it is then propped up or placed in an upright position to form a background. When employing a wall, it is what becomes the background once it is painted.

The following step is to place the subject right in front of the green wall, cardboard or tarpuline. The topic should be positioned within the green frame, so that the green area forms the background. This kind of green screen stages can either be applied in photography, video or film situation, depending on the production intended. Thereafter, the subject is filmed ( according to the storyline ), photographed ( if it is a photograph ) or a video shot taken if it is a video.

After the shots have been taken with the green screen stages as background, editing of the picture, video or film may begin. Pros commonly use categorical software programs to substitute the stages with any desirable background, as decided upon by the actors or subject, to make the green screen effect. Where there is not any application of software, the alternative background can manually be placed in type of a portrait, painting, drawing or a picture. This is very common with photographic productions.
