Photography is the art and technique of obtaining lasting images due to the action of light. It is the process of capturing images and set them in a medium light sensitive material. Based on the principle of the pinhole camera, an image captured by a small hole on a surface, so that the image size is reduced projected image.

What is photography?

The term comes from the Greek φως photography (phos, "light"), and γραφή (Grafe, 'assembly lines, write "), which together means" write / record with light. "Before the term photography is used, known as daguerreotypes, as the discovery was made public by Louis Daguerre although part of its development was due to previous experiences unpublished Joseph-Nicephore Niepce.

Etimology

The invention of the photographic art is the result of combining several technical discoveries. Among the precursors are Chinese philosopher Mo Di, the Greeks Aristotle and Euclid described a pinhole camera in the V and IV centuries BC, Byzantine mathematician Anthemius of Tralles in the sixth century that used a form of camera obscura in his experiments; and four centuries later, the Arab mathematician Alhazen made a clear and thorough study about the camera obscura and pinhole projection.

History

The camera obscura is the image-forming device, while photographic film or electronic sensor is responsible for grasp. Storing captured images depends on the type of camera you being kept in the same movie classic case of machines or any memory device in digital. In the latter case, the resulting image is stored electronically as digital information and can be displayed on a screen or reproduced on paper or film.

Camera Operation

The first stereoscopic images of the history of photography, daguerreotypes are about 1842. Stereoscopic photography was very popular in several decades of the nineteenth century. Many photographers performed using special cameras stereoscopic views of two goals, Cam or a laterally movable target. Classical authors such as J. Laurent, systematically taking stereoscopic views, in addition to normal.

Stereoscopic photography

Normal movies are sensitive to ultraviolet light. One method for performing this type of photography is to use an ultraviolet light source to illuminate the object, so that the camera lens is provided with a filter that allows only the passage of this light. Another method makes use of fluorescence caused by ultraviolet light. The filter chamber is provided which absorbs ultraviolet light and passes fluorescent. An important application of this type of photography is the study of forged documents, and ultraviolet light detected traces of writing removed.
