In this camera, 1 ?-inch-wide films were made of celluloid with a Rätschenmechanismus at up to 46 frames per second on an intermittent lens passing out and exposed it. The exposed film strip was developed photochemically. Served as a playback device, the kinetoscope .
There were at least two copies of Kinetograph.
The term was historically for movie camera and movie projector commonly used.
The Cranz-Schardin method , named after the Balli sufferers Carl Cranz and Schardin Hubert serves the cinematic recording of rapidly occurring processes. By means of a so-called slow-motion camera wireless (also 24-spark camera ), which was developed in 1929 by Cranz and Schardin can, 24 images at a frequency of up to five megahertz are taken (MHz).
The peculiarity of the development of this method is that it allowed the first optical images of the lighting with individual spatially distant sparks with this particular camera on a stationary film purely separate record. This allowed very fast dynamic processes, such as the trajectory of a projectile to be tried. The radio slow motion camera is still in use today.
The radio slow motion consists of both a radio head, from the 24 sparks are ignited, and serve as a light source, and partly from a camera with 24 lenses , in each of the objects matched to the light rays, radio head and camera stand opposite each. The light beam of radio communications is in a lens focused, he is after penetration of the object exactly focused at the camera. The ignition of sparks, which happens very quickly done, at different times, each spark produces an image. This yields a series of 24 photos .
This very short exposure time and the very well-controlled time intervals between flashes permit extremely sharp pricked high speed imaging, may be their frame rates up to 5 Mhz.
Cameras of this type are still used. The advantage of this type of camera is the high resolution of the optical storage on a photographic plate (now some 10 GB), coupled with relatively high frame rates of several MHz.
His school years in Rochester Eastman broke off prematurely because his father died and he had to contribute to the livelihood of the family. From the age of 14 years, Eastman worked as an office boy for an insurance company. His first salary was $ 3 a week. Since this content was not enough to feed the family, Eastman attended evening classes at a business school and was later able to take better paid jobs in the banking industry.
In 1880 he joined the photography industry, focusing initially on the development of photographic dry plates, which he composed in 1881 by Henry Alvah Strong , the Eastman Dry Plate Company founded. From 1884 came the production of negative paper (so-called stripping film ) was added - the company was renamed The Eastman Dry Plate and Film Company .
In 1884, he filed jointly with William Walker, the roll film based on paper (so-called stripping film ) for a patent, after he had bought this invention for the $ 40,000.
The company introduced its first camera in 1886, by Franklin M. Cossitt constructed Eastman Detective Camera , in the summer of 1888 appeared the first camera under the brand name Kodak , the legendary Kodak No. 1 to the camera designer Frank A. Brownell developed for Eastman. On 4 September 1888 Eastman was the trademark "Kodak" to register and received a patent for a roll-film camera.
From 1889 called the company The Eastman Company , the paper film was replaced by that of Henry M. Reichenbach for Eastman developed celluloid film (the so-called American film ), and the celluloid film, however, was already in 1887, Hannibal Goodwin has Eastman; been patented So neither the roll film invented the paper-based or on celluloid base. Even the first plastic, celluloid, is not an American invention. The Hyatt brothers bought the 1868 British patent for Parkesin by Prof. Alexander Parkes, Birmingham, England.
