Camera and its Uses
Camera is an optical tool use for recording pictures, transmitted to some other location which may be stored locally, or both. The pictures might be individual still shoots or sequences of pictures appointing videos or pictures. The word camera comes from camera obscura, which signifies “dark chamber” and is the Latin name of the first device for projecting a picture of outside reality onto a plane surface. The advanced photographic camera developed from the camera obscura. The operation of the camera is identical similar to the functioning of the human eye.
A camera may work with the bright of the color spectrum
or with different parts of the electromagnetic spectrum. A still camera is an optical device which makes a single picture of an object or view, and scans it on an electronic detector or photographic film. All cameras apply the same fundamental design: light enters an enclosed box through with a converging lens and a picture is recorded on a light-sensitive medium. The duration of time is being controlled by shutter mechanism that light can move into the camera. Most photographic cameras have works that permit somebody to see the picture to be recorded, allow for a desired section of the scene to be in focus, and to control the exposure so that it is not too shiny or too dark. A display, often a liquid crystal display (LCD), allows the user to see scene to be recorded and settings such as ISO speed, exposure, and shutter speed.
A still camera works similarly to a video camera or a movie camera, except it records a series of stable images in rapid sequence, generally at a rate of 24 frames per second. Once the images are blended and showed in order, the trick of motion is accomplished.
Traditional camera catch light onto plate or film
Video and digital cameras utilize an electronic image detector, generally a charge coupled device (CCD) or a CMOS detector to capture pictures which can be transmitted or stored in a memory card or some other storage within the camera for afterward processing or replay. Cameras that capture a lot of images in succession are called movie cameras or as ciné cameras in Europe; those configured for single pictures are still cameras.
However these categories overlap as still cameras are frequently accustomed capture moving pictures in special effects function and a lot of advanced cameras can rapidly shift between still and motion recording modes.
