Image Capture Traditional cameras capture light onto photographic film or photographic plate. • Photographic film is a chemically reactive material that records a fixed or still image. • Photographic plate w ere far superior to film quality imaging because they were extremely stable,especially in large-format frames for wide-field imaging.
Lens The Lens is undoubtedly the most important component of the Camera. It takes the beams of light bouncing off an object and focuses this light on the image plane so that a real image is formed that can be photographed. Aperture
Focus Due to the optical properties of photographic lenses, only objects within a limited range of distances from the camera will be reproduced clearly. The process of adjusting this range is known as changing the camera's focus.
Exposure Control the total amount of light allowed to fall on the photographic medium (photographic film or image sensor) during the process of taking a photograph. the brightness of the scene controls the amount of light that enters the camera during a period of time.
Shutters determines how long the film is exposed to light or to the image coming from the lens. Shutters are of two types: leaf shutter the one located just behind the lens focal plane shutter is located in front of the lens
