Have You Ever Wondered..!!
How does a green screen work?
What is chromakeying?
Why is green the most popular color of screen for chromakeying?
Have you ever seen a movie in which a superhero flies through the sky? You can see all the skyscrapers whizzing by in the background, and it looks so cool. Have you ever WONDERed how movie makers film such shots?
Well, we’re here to tell you the secret. And the secret is: there are really superheroes and you just have to catch them in action! OK, not really, but the special effects professionals who work on movies are like superheroes, because they have invented some incredible ways to create special effects shots that will knock your socks off!
You don’t have to watch a superhero movie to see special effects in action, though. All you need to do is turn on the news and watch the local weather forecast. Have you ever noticed how the meteorologist sometimes stands in front of a map with moving graphics? Those scenes are created in much the same way that those cool movie special effects are created.
The green screen is an integral part of the special effects process known formally as chromakey. Chromakey allows television producers and movie makers to use advanced technology to superimpose their subjects onto an unlimited number of different virtual backgrounds.
When a superhero movie is filmed, the actor portraying the superhero might be filmed in front of a green screen lying on his stomach with a huge fan blowing his hair and cape back behind him. Chromakeying can then replace that green background with a moving image of the night skyline behind the actor, making it appear as if he is flying through the sky.
Some of you may be WONDERing if screens have to be green for chromakeying to work. The answer is no! Any color can be isolated and removed via chromakeying. In fact, many movie makers use blue screens. You could even use chromakey to remove red, purple, orange, yellow, pink or blue.!
So why is green such a popular color for screens? The answer to that question lies in the concept of contrast. The screen being used must be different from — contrast with — the actors being filmed. The shade of bright green often used for green screens happens to be a color that very few actors are likely to wear, so it’s easier to isolate and make transparent.
