Which statement is true about shutter angle and exposure?

• A. A smaller shutter angle requires more light
• B. A smaller shutter angle requires less light
• C. Shutter angle does not affect exposure
• D. Shutter angle only affects color

Answer: (A)

Shutter angle controls how long the camera’s sensor is exposed to light for each frame. Exposure depends on light amount times exposure time, so when you reduce the shutter angle you shorten the time the sensor is open. That means less light hits the sensor per frame, so to keep the image properly exposed you need more light (or a larger aperture or slower frame rate). This is why a smaller shutter angle requires more light to maintain the same exposure. The other statements don’t fit because exposure does change with shutter angle, and it’s about brightness and motion perception, not color only.
