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

André Kertész (July 2, 1894 – September 28, 1985) born Andor Kertész, was a Hungarian-born photographer distinguished by his photographic composition and by his early efforts in developing the photo essay. In the early years of his lengthy career, his then-unorthodox camera angles, and his unwillingness to compromise his personal photographic style, prevented his work from gaining wider recognition. Even towards the end of his life, Kertész did not feel he had gained worldwide recognition. The first photographer to have an exposition devoted to his work, he is recognized as one of the seminal figures of photojournalism, if not photography as a whole.

Dedicated by his family to work as a stock broker, Kertész was an autodidact and his early work was mostly published in magazines. This would continue until much later in his life when he ceased to accept commissions. He served briefly in WWI and began to form dreams to move to Paris, which he realised in 1925, against the wishes of his family. There he was involved with the artistic melting pot of immigrates and the dadaist movement, and achieved critical and commercial success. The imminent threat of WWII pushed him to immigrate again to the United States, where he had a more difficult life and needed to rebuild his reputation through commissioned work. He would take offense with several editors that he felt did not recognize his work. In the 1940s and '50s he stopped working for magazines and began achieved greater international success. Despite the numerous and awards he collected over the years, he still felt unrecognized, a sentiment which did not change even into his death.

Slr-cross-section
The single-lens reflex (SLR) is a type of camera that uses a movable mirror placed between the lens and the film to project the image seen through the lens to a matte focusing screen. Most SLRs use a roof pentaprism or pentamirror to observe the image via an eyepiece, but there are also other finder arrangements, such as the waist-level finder or porro prisms.

Large format SLR cameras were first built in the early years of the 20th century. The Ihagee Kine-Exakta was the first 35 mm SLR and it was truly influential. Further Exakta models, all with waist-level finders, were produced up to and during World War II. Another ancestor of the modern SLR camera was the Swiss-made Alpa, which was innovative, and proved influential for the later Japanese cameras. The first solution for an eye-level viewfinder was patented in Hungary during the war,—more precisely, on August 23, 1943, by Jenő Dulovits. The first 35mm camera that had one implemented was the Duflex, designed by Dulovits. This camera utilised a system of mirrors to provide a laterally correct, upright image in the eye-level viewfinder. The Duflex, which went into serial production in 1948, was also the world's first SLR with an instant-return (a.k.a. autoreturn) mirror.
