What is bluescreen?

Bluescreen is a process of special effects used in movie, television, video and recently in the world of computers. Bluescreen, Greenscreent, or Bluescreen display, is used to create an illusion of a background that is not really there when filming. Hollywood blockbusters, such as Star Wars and Harry Potter films, use bluescreen to transport actors to exciting worlds that previously existed only in imagination.

creating bluescreen image, the actor is photographed or filmed in front of a balanced, clean blue background. The image is then usually transmitted to the computer and the blue background is replaced by another image. This is known as a floorboard. Bluescreen images can be filmed optically for movies or static photos, digitally for computer images or electronically for video.

The reason why blue is preferred for this process is that the most common color in the scenes are peach shades; Blue is the most common color. SinceE blue is the opposite color for peach, it is easier to avoid conflicts between colors. Red and green were also used, but cameras and film are more sensitive to blue light.

Another term for the Bluescreen process is chroma-key . It is only a television process and is based on a key with brightness. It works by setting the brightness level for the image and then cutting anything above or below the brightness. Think about it as a keyhole where only a picture remains in the foreground and everything else is darkness. This is usually used to create titles on TV.

Bluescreen has become such a sophisticated technique that it is now virtually impossible to recognize the difference between special effects and real film locations. This process can transport actors anywhere in the world or from this world without actually leaving the studio. It can take you to prehistoric times or transport to space.

Interactive computer games are increasingly using Bluescreen technology. Hollywood actors use video games to include movie clips from their latest films as the Bluescreen processing process can appear in the games themselves. In the future, these games will become indistinguishable from movies - the only difference is that you can control the actors. Thanks to Bluescreen technology, it should not be too long to appear in our own film or play with our favorite actors.
