A camera is an optical instrument for recording images that can be stored locally, transmitted to another location. The camera may be individual photographs or sequences of images that make up movies or movies. The camera is a remote device because it detects substances without physical contact the word camera comes from a dark camera and the original device is projecting an image of external reality on a flat surface. The modern camera evolved from the dark the Camera function is very similar to the human eye.
A Camera can operate with visible spectrum light or with other parts of the electromagnetic spectrum. A still image camera is an optical drive that creates a single image of an object or scene and records it on an electronic sensor or photographic movie. All cameras use the same basic design light that enters a closed box through a converging lens and an image is recorded on a light-sensitive medium, primarily a transition metal halide. A shutdown mechanism regulates how long the light can enter the camera. Camera feature features that allow a person to see the scene to be recorded, focus a desired part of the scene and control exposure so that it is not too light or dim. A screen often makes it possible for a user to display the scene to be recorded and settings such as exposure rate and shutter speed.
A camera movie works in the same way as a still camera, except that it records a series of still images in quick succession, usually at a speed of 24 frames per second. When the images are combined and displayed in order, the illusion of the movement is achieved. Prior to the development of the camera, it had been known for hundreds of years that substances such as silver salts darkened when subjected to sunlight was due to light in themselves and not affected by heat or exposure to air from exposure to light becomes insoluble in an ammonia solution. Camera for creating Wedgwood pictures placed elements such as leaves and insect wings in ceramic pots coated with silver nitrate and exposed the setting to light.
