Hubert Schardin
Hubert Hermann Reinhold Schardin (17 June 1902 Plassow – 27 September 1965 in Freiburg im Breisgau) was a German ballistics expert, engineer and academic who studied in the field of high-speed photography and cinematography. He also was the director of the German-French Research Institute (ISL) in Saint-Louis (France) and founder and director of the Fraunhofer Society Institute for High-Speed Dynamics - Ernst-Mach-Institut (EMI) - in Freiburg im Breisgau. Scientific importance The main importance of Schardin's scientific activities is in high-speed physics. He extended the research of Ernst Mach and Fritz Ahlborn, resulting in more than 1,000 publications. He influenced the development of electro- and high-speed exposures, electro-optical photography and high-speed cinematography with illumination by electric spark and flash x-rays. He developed high-speed measurement techniques, at first for the specific problems of ballistics, to a general scientific level of instrumentat ...

Shadowgraph
Shadowgraph is an optical method that reveals non-uniformities in transparent media like air, water, or glass. It is related to, but simpler than, the schlieren and schlieren photography methods that perform a similar function. Shadowgraph is a type of flow visualisation. In principle, a difference in temperature, a different gas, or a shock wave in the transparent air cannot be seen by the human eye or cameras. However, all these disturbances refract light rays, so they can cast shadows. The plume of hot air rising from a fire, for example, can be seen by way of its shadow cast upon a nearby surface by the uniform sunlight. Sunlight shadowgraph Some aquatic predators detect their transparent prey by way of their shadows cast upon the ocean floor. It was Robert Hooke who first scientifically demonstrated the sunlight shadowgraph and Jean-Paul Marat who first used it to study fire. A modern account of shadowgraphy is given by Gary S. Settles.

Photographers From Berlin
A photographer (the Greek φῶς (''phos''), meaning "light", and γραφή (''graphê''), meaning "drawing, writing", together meaning "drawing with light") is a person who makes photographs. Duties and types of photographers As in other arts, the definitions of amateur and professional are not entirely categorical. An '' amateur photographer'' takes snapshots for pleasure to remember events, places or friends with no intention of selling the images to others. A ''professional photographer'' is likely to take photographs for a session and image purchase fee, by salary or through the display, resale or use of those photographs. A professional photographer may be an employee, for example of a newspaper, or may contract to cover a particular planned event such as a wedding or graduation, or to illustrate an advertisement. Others, like fine art photographers, are freelancers, first making an image and then licensing or making printed copies of it for sale or display. So ...

Film People From Freiburg Im Breisgau
A film also called a movie, motion picture, moving picture, picture, photoplay or (slang) flick is a work of visual art that simulates experiences and otherwise communicates ideas, stories, perceptions, feelings, beauty, or atmosphere through the use of moving images. These images are generally accompanied by sound and, more rarely, other sensory stimulations. The word "cinema", short for cinematography, is often used to refer to filmmaking and the film industry, and to the art form that is the result of it. Recording and transmission of film The moving images of a film are created by photographing actual scenes with a motion-picture camera, by photographing drawings or miniature models using traditional animation techniques, by means of CGI and computer animation, or by a combination of some or all of these techniques, and other visual effects. Before the introduction of digital production, series of still images were recorded on a strip of chemically sensitize ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
