Introduction

Lens and mounting of a large-format camera

Photography is the science, art, application and practice of creating durable images by recording light or other electromagnetic radiation, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film. Photography is employed in many fields of science, manufacturing (e.g., photolithography), and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication.

Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing. The result with photographic emulsion is an invisible latent image, which is later chemically "developed" into a visible image, either negative or positive depending on the purpose of the photographic material and the method of processing. A negative image on film is traditionally used to photographically create a positive image on a paper base, known as a print, either by using an enlarger or by contact printing.

Selected biography

Mathew Brady
Mathew B. Brady (ca. 1823January 15 or January 16[1], 1896) was a celebrated photographer whose rise to prominence occurred largely in the years preceding and during the American Civil War. Following the conflict, a war weary public became disinterested in seeing photos of the war, and Brady’s popularity and practice declined.

Brady's efforts to document the Civil War on a grand scale by bringing his photographic studio right onto the battlefields earned Brady his place in history. Despite the obvious dangers, financial risk, and discouragement of his friends he is later quoted as saying "I had to go. A spirit in my feet said 'Go,' and I went." His first popular photographs of the conflict were at the First Battle of Bull Run, in which he got so close to the action that he only just avoided being captured.

Panoramic photography is a style of photography that aims to create images with exceptionally wide fields of view, but has also come to refer to any photograph that is cropped to a relatively wide aspect ratio (see Panoramic format) While there is no formal definition for the point at which "wide-angle" leaves off and "panoramic" begins, truly panoramic image are thought to capture a field of view comparable to, or greater than, that of the human eye - about 160° by 75° - and should do so while maintaining detail across the entire picture. The resulting images are panoramic, in that they offer an unobstructed or complete view of an area - often, but not necessarily, taking the form of a wide strip. A panoramic photograph is really defined by whether the image gives the viewer the appearance of a "panorama," regardless of any arbitrary technical definition.
