Introduction to Photography

Throughout this week I have been learning and doing practical activities about photography. The definition of photography is the process, activity and art of creating either moving or still pictures by recording on a sensitive such as a photographic film. It could also be an electronic sensor. Light patterns reflected or emitted from object active a sensitive chemical or electrical sensor during a timed exposure. This is 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.

Genres

There are many different genres of photography. They are spread from Black and white photography which we have been creating this week, to paparazzi photography. The many different types of genres are listed as: Aerial, black and white, commercial, documentary, fashion, fine art, forensic, glamour, high speed, illustration, landscape, nature, paparazzi, photojournalism, portrait, still life, stock, underwater and wedding.

There are many devices and parts to what a photograph has to go through for it to actually produce a picture. For example a camera, this is a device that records images; this can be either as still images or as a moving image, known as a movie or video. An early mechanism of projecting image where an entire room functional as a real time imaging system the modern camera evolved from the camera obscure.

Shutter, in photography a shutter is a device which allows light to pass for a determined period of time for the purpose of exposure photography film or a light sensitive electronic sensor to light capture a permanent image of a scene. There is also a shutter speed. This determines how long you hold the shutter down.

Lens

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

Aperture

In optics and aperture is a hole or an opening through which light travels. In photography this can be measured in increments called f.stops. The size of the aperture and the brightness of the scene control the amount of light that enters the camera during the period of time and the shutter controls the length of time that the lights hit the recording surface. Equivalent exposes can be made which a larger aperture and a faster shutter speed slowed down.
