Function Of Camera

The camera is the image-forming device with a silicon electronic image sensor or a photographic film as the sensing medium. The recording medium can be the film itself, or a digital electronic or magnetic memory. But how does camera work? Let us look into the function of camera, which is the prime focus of the page.

For the right functioning of camera, the first step the photographers take is to control the camera and lens. The purpose behind is to "expose" the light recording material or the film to the required amount of light to make a "latent image" or "raw file". This after suitable processing and photography techniques is transformed to a usable image. Digital cameras employ an electronic image sensor founded on light-sensitive electronics such as charge-coupled device (CCD) or complementary metal-oxide-semiconductor (CMOS) technology. The resultant digital image is stored up electronically, but can be replicated on paper or film.

Moving on with the Camera function, the movie camera uses photographic techniques of taking quick sequence of photographs on strips of film. It takes a sequence of images, where each is called a "frame", which is in contrast to a still camera, which arrests a single shot at a time. This is done through an intermittent mechanism, where the frames are later played back in at a specific speed a movie projector. The precise speed is called the "frame rate”, that is the number of frames per second. While viewing, the human’s eyes and brain combine the separate images to generate the illusion of motion.

The function of camera, in most but certain specialized cameras, basically involves the process of acquiring a usable exposure, which must engage the use of a few controls manually or automatically. This is to make sure that the photograph is not only clear, and sharp, but also well illuminated.

So, how does camera function? Well, we hope you have a clear idea about the answer after going through the above article. The photographer should be well aware of the basic various photography techniques and processes for the right functioning of camera, so as to get the desired results.
