Bosco Tech’s Green Screen Technology: The Background Comes to the Foreground

Soaring over the Los Angeles skyline, swimming with a great white shark, or hurtling through outer space—have been seen those images in countless movies and television programs. It’s called green screen technology and it puts characters anywhere a director’s imagination calls for.

Also known as Chroma Key, green screen (or blue screen) technology is a special effects technique used for “compositing” two images or video streams together based on color hues. Used in many fields to remove a background from a subject with a new one, the technique is most often seen in the news broadcasting, motion picture and video game industries.

When the weather person is doing the weather, he or she is standing in front of a green screen. Why the use of green (or blue) screens? Though the chroma keying effect can be done with backgrounds of any color, the use of green (or blue) screens is commonly employed because it differs most distinctly in hue from most human skin colors.

Students of Bosco Tech’s Media Arts and Technology are now using green screens in developing elaborate videos and special effects, while learning about cinematography and advanced computer editing animation.

More importantly, the students learn to prepare  for leadership roles in artistic, engineering, and educational contexts from both an artistic and engineering viewpoint.
