Cinematography
Cinematography (from Ancient Greek κίνημα (kínēma) 'movement' and γράφειν (gráphein) 'to write, draw, paint, etc.') is the art of motion picture (and more recently, electronic video camera) photography.
Cinematographers use a lens to focus reflected light from objects into a real image that is transferred to some image sensor or light-sensitive material inside the movie camera. These exposures are created sequentially and preserved for later processing and viewing as a motion picture. Capturing images with an electronic image sensor produces an electrical charge for each pixel in the image, which is electronically processed and stored in a video file for subsequent processing or display. Images captured with photographic emulsion result in a series of invisible latent images on the film stock, which are chemically "developed" into a visible image. The images on the film stock are projected for viewing in the same motion picture.
Cinematography finds uses in many fields of science and business, as well as for entertainment purposes and mass communication.
In the 1830s, three different solutions for moving images were invented based on the concept of revolving drums and disks, the stroboscope by Simon von Stampfer in Austria, the phenakistoscope by Joseph Plateau in Belgium, and the zoetrope by William Horner in Britain.
In 1845, Francis Ronalds invented the first successful camera able to make continuous recordings of the varying indications of meteorological and geomagnetic instruments over time. The cameras were supplied to numerous observatories around the world and some remained in use until well into the 20th century.
William Lincoln patented a device, in 1867 that showed animated pictures called the "wheel of life" or "zoopraxiscope". In it moving drawings or photographs were watched through a slit.
On 19 June 1878, Eadweard Muybridge successfully photographed a horse named "Sallie Gardner" in fast motion using a series of 24 stereoscopic cameras. The cameras were arranged along a track parallel to the horse's, and each camera shutter was controlled by a trip wire triggered by the horse's hooves. They were 21 inches apart to cover the 20 feet taken by the horse stride, taking pictures at one-thousandth of a second. At the end of the decade, Muybridge had adapted sequences of his photographs to a zoopraxiscope for short, primitive projected "movies", which were sensations on his lecture tours by 1879 or 1880.
Four years later, in 1882, French scientist Étienne-Jules Marey invented a chronophotographic gun, which was capable of taking 12 consecutive frames a second and recording all the frames of the same picture.
