What is the primary use of 'green screen' technology?

• A. To create physical models for scenes
• B. To assist with sound recording
• C. To allow for dynamic backgrounds in post-production
• D. To improve visual clarity

Answer: (C)

The primary use of 'green screen' technology is to allow for dynamic backgrounds in post-production. This technique, also known as chroma keying, involves filming a subject in front of a green backdrop, which can later be replaced with a different image or video during the editing phase. This method enables filmmakers to create a wide range of environments and visual effects that would be difficult or expensive to achieve practically on set. For instance, actors can be seamlessly placed in fantastical locations, outer space, or any setting that isn't physically feasible to film in. The versatility of green screen technology has made it a staple in both film and television production, allowing for creative storytelling and the expansion of the visual narrative beyond the limitations of physical production spaces.
