FUNCTIONS OF CAMERA LENS APERTURE SHUTTER

SHUTTER:

S H U TT E R In photography a shutter is a device that allow light to pass for a determined period exposing photographic film of a light-sensitive electronic sensor to light in order to capture a permanent image of a scene. A shutter can also be used to allow pulses of light to pass outwards, as seen in a movie projector or a signal lamp.

NORMAL LENS:

NO R M A L LE N S Macro lenses are designed for closed for close-up purpose, computed to give best performance and maximum correction of optical aberrations when subject and image distances are image similar. Typical focal length, for 35mm format, is either 50mm or 100mm, with an aperture range of f/2.8-3.2.

SINGLE-LENS REFLEX:

SI NG L E - LE N S R E F LE X In the single-lens reflex camera, the photographer sees the scene through the ca mera lens. This avoids the problem of parallax which occurs when the view finder or view finder or viewing lens is separated from the taking lens.

Most cameras sold today are digital, and digital camera are incorporated into many devices ranging from mobile phone (called camera phones) to vehicles. Consumers adopted digital camera in 1990s. Professional video cameras transitioned to digital around the 200s-2010s . Finally movie camera transitioned to digital in the 2010s.

PROFESSIONAL VIDEO CAMERA:

P R O FE SS IO N A L VI D E O CAMERA A professional video camera (of ten called a television camera even though the use has spread beyond television) is a high-end device for creating electronic moving image (as opposed to movie camera, that earlier recorder the image on film).
