![]() You would need a blue or green screen behind your subject and fairly specialist lighting (doing it live you have far less error margin/latitude). If you have further questions, don’t hesitate to reach out to us.The only way i've ever done it live was to use a panasonic MX50 video mixer (or similar) with a chroma key function on it. Knowing the differences between the two and which is best for your filming needs is an important part of filmmaking. In short, in the evolution of the green screen, the technique became the standard, but blue screens still have their uses. Most software with chroma key editing features also default to keying out green color. Green screens are also much easier to light than blue and reflect more natural light from the colored walls and floors. Digital cameras gather more information on the green part of the spectrum. The availability of affordable portable green screens opens up even more possibilities for filmmakers. ![]() Green screens came into greater use with the advancement of digital cameras and editing software, so now most studios are painted or appointed with that shade of green using chroma key paint. The last film to use yellow screen was Dick Tracy in the 1990s-the technology eventually petered out. The most famous film to use yellow screen is Mary Poppins (during the penguin waiters and other live-action/animated sequences). The resulting footage could be blended with a background matte. ![]() Briefly, the Walt Disney Company used a technique called the sodium vapor process, also referred to as “yellow screen,” which employed a special camera. Yellow Screenīlue screen was the preferred method for filmmakers for a very long time, though they used green screen on occasion. Later, computers took over the physical overlaying process, as with the film Who Framed Roger Rabbit? and the Star Wars film The Empire Strikes Back. Filmmakers continued to use blue screen for decades afterward. A famous early film that employed blue screen was 1940’s The Thief of Bagdad, showing a genie escaping a bottle, a flying carpet, and more. Then they filmed another scene and laid the films atop each other, producing special effects like flying, invisibility, and more. Actors performed in front of a blue-colored screen. With the arrival of color film, more effects became possible with blue screen. But the use of black screens could only do so much. They blacked out parts of a set, ran the film through the camera again, and thus recorded new footage on the blacked-out parts-an example of this effect is the fields rushing by a window in the 1903 film The Great Train Robbery. ![]() At first, directors used double exposures. ![]() When movies came into vogue, directors and cinematographers experimented with different techniques to create similar backgrounds and effects. Backdrops could be painted on curtains and dropped behind the actors to give the impression of time and place. Screens were used to produce special effects even back in the days of the theater. But how long have green screens been used, and how has the technology changed? Here’s a breakdown of the evolution of the green screen. Green screens can help create many scenes, from superhero battles to a more mundane city scene outside a character’s window. Green screen, also known as chroma key technology, is best known for bringing amazing special effects to the movies. ![]()
