The options available for photographers and videographers have widened with the growing popularity and continuous development of computer graphics today. It is now possible for photographers to come up with a number of variations for a single shot without losing every photo’s aesthetic value. All it takes is ample knowledge of the modern techniques in the application of visual effects.
A popular tool used in videography today is video green screen. This technique gives the director the ability to create any kind of pictures and videos. Basically, it uses a specific software that comes with varied backgrounds to replace the originally blue or green background of the subject during the video shoot. Solid green or blue background is used mainly because these are the colors that are farthest from the color of the human skin. In addition to that, a camera’s lenses are most sensitive to both of these colors. When doing the shoot indoors, a three point light system can be used wherein the entire room is completely lit, and there is not a single shadow or shade in the background of the subject as well as on its face and body. If the video shoot is done outside, it is necessary to make sure that ample sunlight gets to the camera, and that there are no shadows or traces of such on the background as well as on the subject itself. A crease on the muslin cloth used should also be completely avoided. After the video shoot, the pictures or videos are then edited according to the preferred scene by replacing the original background of green or blue with the desired backdrop of choice.
With the use of the video green screen, there are no limits on the outputs one can produce. All kinds of scenarios, sights and backgrounds are possible for any images using this popular technique.
