Time-lapse
Time-lapse photography is a technique in which the frequency at which film frames are captured (the frame rate) is much lower than the frequency used to view the sequence. When played at normal speed, time appears to be moving faster and thus ''lapsing''. For example, an image of a scene may be captured at 1 frame per second but then played back at 30 frames per second; the result is an apparent ''30 times'' speed increase. Similarly, film can also be played at a much lower rate than at which it was captured, which slows down an otherwise fast action, as in slow motion or high-speed photography. Processes that would normally appear subtle and slow to the human eye, such as the motion of the sun and stars in the sky or the growth of a plant, become very pronounced. Time-lapse is the extreme version of the cinematography technique of ''undercranking''. Stop motion animation is a comparable technique; a subject that does not actually move, such as a puppet, can repeatedly be move ...

Koyaanisqatsi
''Koyaanisqatsi'' (), also known as ''Koyaanisqatsi: Life Out of Balance'', is a 1982 American experimental film, experimental non-narrative film directed and produced by Godfrey Reggio with music composed by Philip Glass and cinematography by Ron Fricke. The film consists primarily of slow motion and time-lapse footage of cities and many natural landscapes across the United States. The visual Symphonic poem, tone poem contains neither dialogue nor a vocalized narration: its tone is set by the juxtaposition of images and music. Reggio explained the lack of dialogue by stating "it's not for lack of love of the language that these films have no words. It's because, from my point of view, our language is in a state of vast humiliation. It no longer describes the world in which we live." In the Hopi language, the word means "life out of balance". The film is the first in the Qatsi trilogy, ''Qatsi'' film trilogy: it is succeeded by ''Powaqqatsi'' (1988) and ''Naqoyqatsi'' (2002). T ...

John Ott
John Nash Ott (23 October 1909 – 6 April 2000) was a photo-researcher, writer, photographer, and cinematographer who was an early adopter of many modern photographic practices, including time-lapse photography and full-spectrum lighting. Photography Ott's early career was in finance. He never went to college, although he enrolled in finance courses at Harvard Business School while working for several Chicago area banks. During this period, he developed an interest in time-lapse photography. He made his first time-lapse film in 1927, while he was still in high-school, but did not develop the automated mechanical camera rig which he used in his later films, until 1937. His early amateur films led him to a career in cinematography. In addition to making films, he performed research about the effects of natural lighting on plants, animals, and humans. Initially, Ott's interest in time-lapse movie photography, mostly of plants, was just a hobby. Starting in the 1930s, Ott bought a ...

Stop Motion Animation
Stop motion is an animated filmmaking technique in which objects are physically manipulated in small increments between individually photographed frames so that they will appear to exhibit independent motion or change when the series of frames is played back. Any kind of object can thus be animated, but puppets with movable joints (puppet animation) or plasticine figures (''clay animation'' or claymation) are most commonly used. Puppets, models or clay figures built around an armature are used in model animation. Stop motion with live actors is often referred to as pixilation. Stop motion of flat materials such as paper, fabrics or photographs is usually called cutout animation. Terminology The term "stop motion", relating to the animation technique, is often spelled with a hyphen as "stop-motion". Both orthographical variants, with and without the hyphen, are correct, but the hyphenated one has a second meaning that is unrelated to animation or cinema: "a device for automatica ...

Roman Vishniac
Roman Vishniac (; russian: link=no, Рома́н Соломо́нович Вишня́к; August 19, 1897 – January 22, 1990) was a Russian-American photographer, best known for capturing on film the culture of Jews in Central and Eastern Europe before the Holocaust. A major archive of his work was housed at the International Center of Photography until 2018, when Vishniac's daughter, Mara Vishniac Kohn, donated it to The Magnes Collection of Jewish Art and Life at the University of California, Berkeley. Vishniac was a versatile photographer, an accomplished biologist, an art collector and teacher of art history. He also made significant scientific contributions to photomicroscopy and time-lapse photography. Vishniac was very interested in history, especially that of his ancestors, and strongly attached to his Jewish roots; he was a Zionist later in life.ICP Library of Photographers. ''Roman Vishniac''.

Frame Rate
Frame rate (expressed in or FPS) is the frequency (rate) at which consecutive images (frames) are captured or displayed. The term applies equally to film and video cameras, computer graphics, and motion capture systems. Frame rate may also be called the , and be expressed in hertz. Frame rate in electronic camera specifications may refer to the maximal possible rate, where, in practice, other settings (such as exposure time) may reduce the frequency to a lower number. Human vision The temporal sensitivity and resolution of human vision varies depending on the type and characteristics of visual stimulus, and it differs between individuals. The human visual system can process 10 to 12 images per second and perceive them individually, while higher rates are perceived as motion. Modulated light (such as a computer display) is perceived as stable by the majority of participants in studies when the rate is higher than 50 Hz. This perception of modulated light as steady is known ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slow Motion
Slow motion (commonly abbreviated as slo-mo or slow-mo) is an effect in film-making whereby time appears to be slowed down. It was invented by the Austrian priest August Musger in the early 20th century. This can be accomplished through the use of high-speed cameras and then playing the footage produced by such cameras at a normal rate like 30 fps, or in post production through the use of software. Typically this style is achieved when each film frame is captured at a rate much faster than it will be played back. When replayed at normal speed, time appears to be moving more slowly. A term for creating slow motion film is overcranking which refers to hand cranking an early camera at a faster rate than normal (i.e. faster than 24 frames per second). Slow motion can also be achieved by playing normally recorded footage at a slower speed. This technique is more often applied to video subjected to instant replay than to film. A third technique uses computer software post-processing to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Rife
Royal Raymond Rife (May 16, 1888 – August 5, 1971) was an American inventor and early exponent of high-magnification time-lapse cine-micrography. Rife is known for his microscopes, which he claimed could observe live microorganisms with a magnification considered impossible for his time, and for an "oscillating beam ray" invention, which he thought could treat various ailments by "devitalizing disease organisms" using radio waves. Although he came to collaborate with scientists, doctors and inventors of the epoch, and his findings were published in newspapers and scientific journals like the Smithsonian Institution annual report of 1944, they were later rejected by the American Medical Association (AMA), the American Cancer Society (ACS) and mainstream science. Rife's supporters continue to claim that impulses of electromagnetic frequencies can disable cancerous cells and other microorganisms responsible for diseases. Most of these claims have no scientific research to back t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Health And Light
Health, according to the World Health Organization, is "a state of complete physical, mental and social well-being and not merely the absence of disease and infirmity".World Health Organization. (2006)''Constitution of the World Health Organization''– ''Basic Documents'', Forty-fifth edition, Supplement, October 2006. A variety of definitions have been used for different purposes over time. Health can be promoted by encouraging healthful activities, such as regular physical exercise and adequate sleep, and by reducing or avoiding unhealthful activities or situations, such as smoking or excessive stress. Some factors affecting health are due to individual choices, such as whether to engage in a high-risk behavior, while others are due to structural causes, such as whether the society is arranged in a way that makes it easier or harder for people to get necessary healthcare services. Still, other factors are beyond both individual and group choices, such as genetic disorders. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exploring The Spectrum
Exploration refers to the historical practice of discovering remote lands. It is studied by geographers and historians. Two major eras of exploration occurred in human history: one of convergence, and one of divergence. The first, covering most of ''Homo sapiens'' history, saw humans moving out of Africa, settling in new lands, and developing distinct cultures in relative isolation. Early explorers settled in Europe and Asia; 14,000 years ago, some crossed the Ice Age land bridge from Siberia to Alaska, and moved southbound to settle in the Americas. For the most part, these cultures were ignorant of each other's existence. The second period of exploration, occurring over the last 10,000 years, saw increased cross-cultural exchange through trade and exploration, and marked a new era of cultural intermingling, and more recently, convergence. Early writings about exploration date back to the 4th millennium B.C. in ancient Egypt. One of the earliest and most impactful thinkers of ...

Sunset Time Lapse 31-12-2009
Sunset, also known as sundown, is the daily disappearance of the Sun below the horizon due to Earth's rotation. As viewed from everywhere on Earth (except the North and South poles), the equinox Sun sets due west at the moment of both the spring and autumn equinoxes. As viewed from the Northern Hemisphere, the Sun sets to the northwest (or not at all) in the spring and summer, and to the southwest in the autumn and winter; these seasons are reversed for the Southern Hemisphere. The time of sunset is defined in astronomy as the moment when the upper limb of the Sun disappears below the horizon. Near the horizon, atmospheric refraction causes sunlight rays to be distorted to such an extent that geometrically the solar disk is already about one diameter below the horizon when a sunset is observed. Sunset is distinct from twilight, which is divided into three stages. The first one is ''civil twilight'', which begins once the Sun has disappeared below the horizon, and continues unti ...

Oxford Scientific Film Institute
Oxford () is a city in England. It is the county town and only city of Oxfordshire. In 2020, its population was estimated at 151,584. It is north-west of London, south-east of Birmingham and north-east of Bristol. The city is home to the University of Oxford, the oldest university in the English-speaking world; it has buildings in every style of English architecture since late Anglo-Saxon. Oxford's industries include motor manufacturing, education, publishing, information technology and science. History The history of Oxford in England dates back to its original settlement in the Saxon period. Originally of strategic significance due to its controlling location on the upper reaches of the River Thames at its junction with the River Cherwell, the town grew in national importance during the early Norman period, and in the late 12th century became home to the fledgling University of Oxford. The city was besieged during The Anarchy in 1142. The university rose to domin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
