CAMERA
A camera is an optical instrument that captures a 
visual image. At their most basic, cameras are sealed 
boxes (the camera body) with a small hole (the 
aperture) that allows light in to capture an image on a 
light-sensitive surface (usually photographic film or a 
digital sensor). Cameras have various mechanisms to 
control how the light falls onto the light-sensitive 
surface. Lenses focus the light entering the camera on 
the sensor and the size of the aperture can be 
widened or narrowed to let more or less light into the 
camera, and a shutter mechanism determines the 
amount of time the photosensitive surface (sensor) is 
exposed to the light.
CAMERA
The still image camera is the main instrument in the 
art of photography and captured images may be 
reproduced later as a part of the process of 
photography, digital imaging, photographic printing. 
Similar artistic fields in the moving image camera 
domain are film, videography, and cinematography.
MECHANICS
A camera captures light photons, usually from the 
visible spectrum for human viewing, but in general 
could also be from other portions of the 
electromagnetic spectrum.
All cameras use the same basic design: light enters an 
enclosed box through a converging or convex lens and 
an image is recorded on a light-sensitive medium 
(known as digital sensor) (mainly a transition metal-
halide). A shutter mechanism controls the length of 
time that light can enter the camera.
PRIMARY TYPES
In photography, the single-lens reflex camera (SLR) is 
provided with a mirror to redirect light from the lens 
to the viewfinder prior to releasing the shutter for 
composing and focusing an image. When the shutter 
is released, the mirror swings up and away allowing 
the exposure of the photographic medium and 
instantly returns after the exposure is finished . No 
SLR camera before 1954 had this feature, although 
the mirror on some early SLR cameras was entirely 
operated by the force exerted on the shutter release 
and only returned when the finger pressure was 
released. The Asahiflex II, released by Japanese 
company Asahi (Pentax) in 1954, was the world's first 
SLR camera with an instant return mirror.
