To really understand the process, one should find a studio that uses “chroma key” technology in its film productions. It can take you set by set in gaining knowledge about working with the software programs. Hands-on experience is always the best teacher especially when it comes to this type of technolgy. You have to see for yourself how it works. It is easier to understand when it is physically present and within the reach of the person that is trying to gain more understanding of how it works. We will start at the beginning and go through the whole process.
You can find special areas or rooms that are reserved for chorma key technology assisted movie and video outputs. Some stages can be set up temporarily in a room that has been used for other uses. A wall is usually then used as the screen. Let’s start with the basics to better grasp the idea behind green screen software.
Materials have to be collected that will serve as the background and that could be cardboard, tarpuline or a wall. You can choose a good wall for use in the application. Next, choose the paint and it will be green in which case the background is colored with this paint. It is crucial that the material is of high quality and cannot tear or wrinkle easily. The green screen quality will effect the quality of the images in the final production whether film, video, or a photograph. The material chosen should be very smooth and the paint or hue should appear very bright on the material. Once it has dried and it is propped up to form the background or the wall after drying is used.
Finally, you put the person directly in front of the wall, cardboard or tarpuline but also within the green frame that forms the background. The green area should be the background. You can use this process for photography, film, or video depending on what is required. You can now add the person to the story line and film or photograph it as normal. After the images have been taken this way, the editing can begin. Professionals most likely use certain software programs that alternate the stages with the preferred background of choice to create the green screen effect. Without the use of application software the manual placement of the background could be a portrait, painting, picture or illustration. Photographic productions most often utilize this process.
