Besavilla Cartography Practice Exam

Part of the camera which controls the length of time that light is permitted to pass through the lens.

Shutter Magazine Camera Body Lens Cone Assembly

Correct Answer:

Shutter

Explanation:

The length of time light is allowed to pass through the lens is controlled by the shutter. The shutter opens to let light reach the sensor or film for a measured duration, called the shutter speed. A fast shutter keeps the exposure brief, reducing light and helping freeze action in bright scenes. A slow shutter lengthens the exposure, letting in more light and potentially creating motion blur or overexposure in bright conditions. The other parts mentioned don’t regulate how long light is allowed through: the magazine stores film or data, the camera body houses controls and electronics, and the lens cone assembly is related to mounting and focusing light, not exposure duration.
