Lighting is the second most crucial point. On set, small props like tennis balls are frequently used as visual references for the actors to navigate in the scene. The author must determine in advance what will be physically present in the scene and what will be added later while editing. When using a green screen, the main goal is to plan what is real in the shot and what is not. The goal of keying is to get the background as clean as possible. After removing the green color, the background will be completely transparent, and one can fill this area with another image or video. Keying is the removal of the green background through video editing programs. The footage is recorded on a monochromatic color background in the studio, and the keying process takes place during further video editing. The convenience of green screens is that it becomes possible to create the required background in the frame or scene without expensive outdoor shooting by replacing the studio background with a virtual picture. The software makes combining two or more images in the same frame or scene easy. Other than the obvious reference to the background color, green screen refers to the technology that combines several images in a single composition by replacing and combining backgrounds. But what is the definition of a green screen exactly? However, it is only the skillful work of professional designers, artists, and other specialists, as well as the use of green screens as backdrops on set. The ruins of buildings, interplanetary galaxies, and many special effects seem so realistic that there is practically no doubt about their existence. Your lighting will make or break the final shot and ruin the illusion you're trying to create.Nowadays, when watching even the most fantastic and implausible scenes, the audience completely loses awareness of the illusory nature. One of the most important elements here is lighting. And it can be tempting to simply shoot "whatever" and then rely on "fixing it in post." This is a mistake and your job will be a lot easier if you do it right from the beginning. You can do a lot with post-production software these days. The only way to master any skill is through experience. Raise your shutter speed, motion blur may end up showing a green tint. By keeping the field of view entirely inside the green background, you'll ensure that no edges appear and ruin the effect. Other costume considerationsĭon't wear watches or anything too reflective. This makes it nice and easy for the software to detect that color and fill it in. The whole point of using green as a color for this kind of work is because it's an uncommon color. Now, let's move onto some of the common mistakes you'll want to avoid. Of course, practice makes perfect and don’t be afraid to outsource to someone a little more adept in chroma key and green screen effects. And assuming your background plate is in focus, an out-of-focus subject will stand out (aka look fake) even more. This will avoid green spilling onto the border of your image/subject. This includes quality, color, direction and quantity of the light source(s) in your background plate. Match your backgroundįor example, if using a bright, sun-filled background, you'll want to match that lighting as closely as possible. This requires some lighting tinkering, and maybe some distance between yourself and the screen. Any wrinkles or missing paint will yield a less-than-satisfactory final shot when compositing. Make the backdrop as smooth and even as possible. Green or blueĭepending on your project, green is better than a blue screen so the background is as different as possible from everything else in the shot. For ideal shooting conditions, make sure you optimize your end product with the proper green screen color. Whether you're using a painted wall or hanging green fabric, just make sure it's green - but not just any green.
