Amazing Videos is a reality television series that showcases accidents, disasters, police chases and other extraordinary events that are caught on video camera. These videos normally shown anybody involved in these aforementioned incidents survive nonetheless. Although it is similar in content to the other series Real TV and Maximum Exposure, it takes a more serious tone. Originally, the show appeared on NBC as a timeslot filler program. A new series of episodes of the show were created in 2006 first-run for Spike TV, after a six-year hiatus from the NBC stint.[1]

Until the year 2008, all episodes of the show were narrated by Stacy Keach. From that point on, the season was narrated by Erik Thompson. The show is broadcasted in the UK on Bravo and Channel One, in which David Wartnaby served as the narrator of the first season followed by Lee Boardman in the second season of broadcast in the particular country, and is expected to return in 2012. In Australia, it is shown on the pay-TV channel FOX8. The series was given its own local name titled Global Shockers for the Philippines market and it was hosted by Johnny Delgado.
An episode usually begins with what will be shown later on. After these sequences, the opening statement is said: "These are the incredible true-life stories of people who face their most desperate hour and lived to tell about it. Everything you are about to see is real – real people, real danger, real excitement. Get ready to experience the thrill of a lifetime. You are about to witness... The World's Most Amazing Videos!"

At the beginning of each video shown, the narrator commonly says the place, sometimes followed by the time and date; for example, "San Diego, California, 1995" during Shawn Nelson's M60 Patton tank rampage. The commentary of these events are normally like the action of the persons involved. These videos usually have their stock sound effects added in post-production. There are interviews of persons involved in the event, accounting what's happened. At the end of the video, it shows the summary of how the person or anything survive during this event.

At the end of the episode, the closing statement is said: "These are the astonishing true stories of real people who faced the ultimate danger and lived to tell about it. Join us next time for more on the World's Most Amazing Videos."

UK TV no longer shows the programme after a number of complaints about videos featured. For a while it still aired but highly edited, including the moment of impact in the video would be paused and un-paused to see the aftermath. It was cancelled when the UK broadcasters realised this beat the purpose of the show.
"Photographic" redirects here. For other uses, see Photography (disambiguation).

Photography (derived from the Greek photos- for "light" and -graphos for "drawing") is the art, science, and practice of creating durable images by recording light or other electromagnetic radiation, either chemically by means of a light-sensitive material such as photographic film, or electronically by means of an image sensor.[1] Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. The result in an electronic image sensor is an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing.

The result in a photographic emulsion is an invisible latent image, which is later chemically developed into a visible image, either negative or positive depending on the purpose of the photographic material and the method of processing. A negative image on film is traditionally used to photographically create a positive image on a paper base, known as a print, either by using an enlarger or by contact printing.

Photography has many uses for business, science, manufacturing (e.g. photolithography), art, recreational purposes, and mass communication.
On 1834, in Campinas, Brazil, Hercules Florence, a French painter and inventor, wrote in his diary the word "photographie" to describe his process.[2] As far as can be ascertained, it was Sir John Herschel in a lecture before the Royal Society of London, on March 14, 1839 who made the word "photography" known to the world. But in an article published on February 25 of the same year in a German newspaper called the Vossische Zeitung, Johann von Maedler, a Berlin astronomer, had used the word photography already.[3]

The word photography derives from the Greek φωτός (phōtos), genitive of φῶς (phōs), "light"[4] and γραφή (graphé) "representation by means of lines" or "drawing",[5] together meaning "drawing with light".[6]
Photography is the result of combining several technical discoveries. Long before the first photographs were made, Chinese philosopher Mo Di and Greek mathematicians Aristotle and Euclid described a pinhole camera in the 5th and 4th centuries BC.[8][9] In the 6th century AD, Byzantine mathematician Anthemius of Tralles used a type of camera obscura in his experiments,[10] Ibn al-Haytham (Alhazen) (965–1040) studied the camera obscura and pinhole camera,[9][11] Albertus Magnus (1193–1280) discovered silver nitrate,[12] and Georg Fabricius (1516–71) discovered silver chloride.[13]

Daniele Barbaro described a diaphragm in 1566.[14] Wilhelm Homberg described how light darkened some chemicals (photochemical effect) in 1694.[15] The fiction book Giphantie, published in 1760, by French author Tiphaigne de la Roche, described what can be interpreted as photography.[14]

The discovery of the camera obscura that provides an image of a scene dates back to ancient China. Leonardo da Vinci mentions natural cameras obscura that are formed by dark caves on the edge of a sunlit valley. A hole in the cave wall will act as a pinhole camera and project a laterally reversed, upside down image on a piece of paper. So the birth of photography was primarily concerned with developing a means to fix and retain the image produced by the camera obscura.

The first success of reproducing images without a camera occurred when Thomas Wedgwood, from the famous family of potters, obtained copies of paintings on leather using silver salts. Since he had no way of permanently fixing these reproductions (stabilizing the image by washing out the non-exposed silver salts), they would turn completely black in the light and thus had to be kept in a dark room for viewing.

Renaissance painters used the camera obscura which, in fact, gives the optical rendering in color that dominates Western Art. The camera obscura literally means "dark chamber" in Latin. It is a box with a hole in it which allows light to go through and create an image onto the piece of paper.
