exposure time

Exposure time is the amount of time a camera’s sensor or film is exposed to light when capturing an image. It determines how much light is collected, affecting the brightness and detail of the photo. A short exposure captures quick movements sharply, ideal for action shots, while a longer exposure gathers more light, producing brighter images in low light but may cause motion blur if anything moves during the shot. Adjusting exposure time helps photographers control the final appearance of their images, balancing clarity, brightness, and the sense of motion.
