In filming, is blue screen the same as green screen?

Answer 1

Depending on conditions, there can be some big differences.
Your lighting, foreground objects, and people can all affect the appearance in post. If a character's costume or set decor is similar to one of the colors (b/g), the other must be used. Some people with bright blue eyes need to work in front of green. F.Y.I. A specific shade of red also works. Some will say you can use ANY color. While technically that's true, real world conditions and the subject matter that you're filming dictate what colors you CAN use. You can remove any color from an image in post, but depending on the color removed, it will just ruin the shot. Sometimes it just comes down to a fiscal issue. Do I really want to have a new 80 ft x 60 ft fuchsia-colored cloth custom made when I already have both green and blue sitting in my warehouse? You can almost always make blue or green work.

Answer 2

In a short answer, yes. All the blue/green screen is used for is for color mapping/matting to digitally edit in a different background. The reason for using a blue screen is if the actors or something in the foreground the director wishes to keep in the film is green. Technically any color screen can be used to make a color map that is not of the same or close to the same color that is wished to be kept in the film.

Answer 3

green screen is usualy where they have to take something out and put something in.

a good example would be Forrest Gump and Lt Dan

in the scene where he jumps over the side of the ship, he wore a blue sock over his legs. a green screen was where the ocean is in the shot. so using the sock and the green screen they then took out a section of the rail so he actually swung through the opening but appeared to swing over it.

blue screen is usuallly just someone imposing themselves into a scene. like it might be someone standing in space well their not really going to be in space.

but with blue screen they are.

Answer 4

Yes the variants in colours is down to choice, they are used because the colours themselves are easily distinguishable in comparison to those who are in front of the screens, making it simple to impose a background.

Answer 5

It is basically the same.

There may be slightly different things you can do with them, but they serve the same basic purpose.

Answer 6

there are some differences but they are used for practically the same thing

Answer 7

Yes. They are both used in CGI movies, and it really doesn't matter which one is used.

Answer 8

no
