What does "green screen" technology allow filmmakers to do?

• A. To capture high-resolution images during filming
• B. To replace a green background with virtual settings
• C. To improve audio quality in outdoor scenes
• D. To create special effects in camera

Answer: (B)

"Green screen" technology allows filmmakers to replace a green background with virtual settings, enabling them to create complex visual environments that would be difficult or impossible to film in real life. This technique relies on the color green (or sometimes blue) because these colors are often not present in human skin tones, making it easy to isolate and remove the background in post-production. When the green area of the frame is keyed out, it can be filled with any digital image or footage, allowing for seamless integration of different elements, such as actors performing against a fantastical landscape or action sequences set in outer space. The functionality provided by green screen technology is particularly crucial in genres such as science fiction or fantasy, where elaborate settings contribute significantly to storytelling. The ability to invent and transport an audience into alternate realities is one of the defining features of modern filmmaking, and green screen plays a foundational role in achieving that artistry.
