Photography

Photography.
Is the process, activity and the art of creating skill or moving pictures by recording radiation on a sensitive medium, such as photographic film, or an electronic sensor. Light patterns reflected or emitted from objects activate a sensitive chemical or electronic sensor during a timed exposure, usually thought a photographic lens in a device know as a camera that also stores the resulting information chemically or electronically. Photography has many uses for business, science, art and pleasure.

A Camera
A Camera is a device that records images, either as a still photography or as moving images know as videos or movies. The term comes from the term Camera Obscura (Latin for “Dark Chamber”), an early mechanism of projecting images where an entire room functioned as a real-time imaging system; the modern camera evolved from the camera obscura.

Shutter
In photography a shutter is a device that allows light to pass for a determined period of time, for the purpose of exposing photographic film or a light sensitive electronic sensor to light to capture a permanent image of a scene.

Aperture
In optics, an aperture is a hole or an opening through which light travels. In photography this can be measured in increments called f-stops.

Lens
The lens of a camera captures the light from the subject and brings it to a focus on the film or decoder.

Exposure Control
The size of the aperture and the brightness of the scene controls the amount of light that enters the camera during a period of time, and the shutter controls the length of time that the light hits the recording surface. Equivalent exposures can be made with a larger aperture and a faster shutter speed or a corresponding smaller aperture and with the shutter speed slowed down.
