Shutter speed refers to the amount of time each frame is exposed for.

• A. The color balance of the scene
• B. The frame rate at which the camera records
• C. The amount of time that each frame is exposed
• D. The type of camera sensor used

Answer: (C)

Shutter speed is about how long the camera’s sensor is exposed to light for each frame. This exposure duration directly controls brightness and motion appearance in the image: a longer exposure per frame lets in more light and can create motion blur, while a shorter exposure keeps things brighter or darker and reduces blur. The other ideas refer to different concepts—color balance (white balance) adjusts color accuracy, frame rate is how many frames are captured per second, and the sensor type affects image characteristics but not how long each frame is exposed.
