exposure time
Light collection period
Exposure time is how long a camera's sensor or film receives light during a single shot.
Longer exposure times let in more light, useful in dim conditions but causing motion blur; shorter times freeze action but require brighter conditions.
The night sky photo required a thirty-second exposure time.
Also called shutter speed.
