Question

Chroma Keying is the technical term for using green screens. When the technique was invented, however, the screens weren't green. What color screen was used instead?

1) Blue
2) Red
3) Yellow
4) White

Answer 1

The technique of chroma keying, also known as green screening, was originally done using blue screens, not green screens.

Step-by-step explanation:

The correct answer is 2) Blue.

Chroma Keying, also known as green screening, is a technique used in film and television production to superimpose one image or video onto another. The technique involves replacing a specific color, typically green or blue, with a background image or video using special software.

When the technique was first invented, blue screens were used instead of green screens. This is because blue screens were found to provide a better separation between the foreground subject and the background image. However, with advancements in technology and the use of digital cameras, green screens became more popular due to the higher sensitivity of digital sensors to the color green, resulting in smoother and more accurate keying.
