/fәˈtɒɡrәfi/ ) (from Greek φωτο and γραφία) is the process, activity and art of creating still or moving pictures by recording radiation on a sensitive medium, such as a 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 through a photographic lens in a device known as a camera that also stores the resulting information chemically or electronically. Photography has many uses for business, science, art and pleasure.
The genre's of photography include:

is a device that records images, either as a still photograph or as moving images known as videos or movies. The term comes from the
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.
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.
optics, an aperture is a hole or an opening through which light travels. In Photography this can be measured in increments called f-stops.
The of a camera captures the light from the subject and brings it to a focus on the film or detector.
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.
