Time-lapse photography

Time-lapse photography is a technique whereby the frequency at which film frames are captured (the frame rate) is much lower than that 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 once every second, then played back at 30 frames per second; the result is an apparent 30 times speed increase. Time-lapse photography can be considered the opposite of high speed photography or slow motion.

Processes that would normally appear subtle to the human eye, e.g. the motion of the sun and stars in the sky, become very pronounced. Time-lapse is the extreme version of the cinematography technique of undercranking, and can be confused with stop motion animation.

History

Some classic subjects of timelapse photography include:

The technique has been used to photograph crowds, traffic, and even television. The effect of photographing a subject that changes imperceptibly slowly, creates a smooth impression of motion. A subject that changes quickly is transformed into an onslaught of activity.

Time Lapse

Time Lapse is the first live album by guitarist Steve Hackett. The album is drawn from live performances at the Savoy Theater in New York City (during the Cured tour) and at Central TV Studios in Nottingham.

Space station

A space station, also known as an orbital station or an orbital space station, is a spacecraft capable of supporting a crew, which is designed to remain in space (most commonly as an artificial satellite in low Earth orbit) for an extended period of time and for other spacecraft to dock. A space station is distinguished from other spacecraft used for human spaceflight by lack of major propulsion or landing systems. Instead, other vehicles transport people and cargo to and from the station. As of September 2014 two space stations are in orbit: the International Space Station, which is permanently manned, and China's Tiangong-1 (which successfully launched on September 29, 2011), which is unmanned most of the time. Previous stations include the Almaz and Salyut series, Skylab and most recently Mir.

Today's space stations are research platforms, used to study the effects of long-term space flight on the human body as well as to provide platforms for greater number and length of scientific studies than available on other space vehicles. Each crew member staying aboard the station for weeks or months, but rarely more than a year. Most of the time crew remain at station but its not necessary that crew should have to be stay at station. Since the ill-fated flight of Soyuz 11 to Salyut 1, all manned spaceflight duration records have been set aboard space stations. The duration record for a single spaceflight is 437.7 days, set by Valeriy Polyakov aboard Mir from 1994 to 1995. As of 2013, three astronauts have completed single missions of over a year, all aboard Mir.

International Space Station

The International Space Station (ISS) is a space station, or a habitable artificial satellite, in low Earth orbit. Its first component launched into orbit in 1998, and the ISS is now the largest artificial body in orbit and can often be seen with the naked eye from Earth. The ISS consists of pressurised modules, external trusses, solar arrays, and other components. ISS components have been launched by Russian Proton and Soyuz rockets as well as American Space Shuttles.

The ISS serves as a microgravity and space environment research laboratory in which crew members conduct experiments in biology, human biology, physics, astronomy, meteorology, and other fields. The station is suited for the testing of spacecraft systems and equipment required for missions to the Moon and Mars. The ISS maintains an orbit with an altitude of between 330 and 435 km (205 and 270 mi) by means of reboost manoeuvres using the engines of the Zvezda module or visiting spacecraft. It completes 15.54 orbits per day.

Peter Gabriel

Peter Brian Gabriel (born 13 February 1950) is an English singer-songwriter, musician and humanitarian activist who rose to fame as the original lead singer and flautist of the progressive rock band Genesis. After leaving Genesis in 1975, Gabriel went on to a successful solo career, with "Solsbury Hill" his first single. His 1986 album, So, is his most commercially successful, and is certified triple platinum in the UK and five times platinum in the U.S. The album's biggest hit, "Sledgehammer", won a record nine MTV Awards at the 1987 MTV Video Music Awards, and it remains the most played music video in the history of MTV.

Gabriel has been a champion of world music for much of his career. He co-founded the WOMAD festival in 1982. He has continued to focus on producing and promoting world music through his Real World Records label. He has also pioneered digital distribution methods for music, co-founding OD2, one of the first online music download services. Gabriel has been involved in numerous humanitarian efforts. In 1980, he released the anti-apartheid single "Biko". He has participated in several human rights benefit concerts, including Amnesty International's Human Rights Now! tour in 1988, and co-founded the WITNESS human rights organisation in 1992. Gabriel developed The Elders with Richard Branson, which was launched by Nelson Mandela in 2007.
