Your local weatherperson uses it to look like they’re standing in front of a cool weather map.īut you don’t have to be a big-shot movie director or even a local TV station to enjoy the many benefits green screen (or, as it’s technically called - chroma key) offers. Selecting a region changes the language and/or content on studios use green screen to create all kinds of incredible special effects. “A blue screen gives you a much stronger contrast with blond.” It’s almost a little bit translucent and you get color spill,” Yeager says. “Blond hair can be difficult to key out on a green screen because of the way light reflects through it. But even colors that don’t match the background can still cause a problem. If the scene you’re shooting absolutely requires a character to wear green, you should use a blue background, and vice versa. This can make the keying process more difficult, so you want to avoid color spill as much as you can.” Color spill is when the color of the chroma key background is reflected back onto the actor. “It’s darker, so it’ll reflect less light back on them, which means less color spill to deal with in post-production. ![]() “If you’re trying to composite around an actor in a night scene, you want to go with a blue screen,” Yeager recommends. But a blue screen can be handy in scenes where you don’t need so much light. A green background has a much higher luminosity than a blue one, making a green screen a better choice for daytime scenes when you want your shots to look bright and well lit. One key factor is luminance, or the amount of light a color reflects. Whether you use a blue screen or a green screen ultimately depends on the circumstances of your shoot. This is because the chroma key process keys out and removes everything that is the same color as the background screen. For example, if an actor wears blue clothing in front of a blue screen, their body will be chroma keyed out of the shot along with the screen behind them. This is why it’s important to make sure your actors don’t wear anything that matches the color of the screen behind them. But we have the video editing technology to lock onto any shade of whatever color we want.”īlue or green colors are popular backgrounds for filmmaking because they’re different from most human skin tones, hair colors, and clothing. “Sometimes that’s green, because it gives you the best separation. “Chroma key is when you lock onto a specific color that’s different from anything else in the shot and eliminate it completely,” says director and cinematographer Steven Bernstein. “But even in modern films they still use blue screens for specific reasons. With digital cameras, green is more popular,” says filmmaker Charles Yeager. “In the old days with film, blue made it easier to key things. Even if you’re an amateur shooting a short film in your backyard or a YouTuber making a tutorial video, hanging something as simple as a green or blue sheet in the background of a shot gives you the power to add stunning VFX during the post-production process by using a technique called chroma key compositing. But you don’t have to be a professional filmmaker to enjoy the benefits of a blue or green screen. If you’ve ever watched a behind-the-scenes special for a Hollywood blockbuster, you’ve probably seen actors performing in front of a green or blue background.
