The Amazing Race is a reality television game show in which teams of two people, who have some form of a preexisting personal relationship, race around the world in competition with other teams. Contestants strive to arrive first at "Pit Stops" at the end of each leg of the race to win prizes and to avoid coming in last, which carries the possibility of elimination or a significant disadvantage in the following leg. Contestants travel to and within multiple countries in a variety of transportation modes, including airplanes, hot air balloons, helicopters, trucks, bicycles, taxicabs, car, jeepneys, trains, buses, boats, and by foot. Clues provided in each leg lead the teams to the next destination or direct them to perform a task, either together or by a single member. These challenges are related in some manner to the country wherein they are located or its culture. Teams are progressively eliminated until three are left; at that point, the team that arrives first in the final leg is awarded the grand prize. Created by Elise Doganieri and Bertram van Munster, the original series has aired in the United States since 2001 and has earned thirteen Primetime Emmy Awards, including every award from 2003 to 2012 for "Outstanding Reality-Competition Program", except in 2010 when Top Chef won. Emmy-award-winning New Zealand television personality, Phil Keoghan, has been the host of the U.S. version of the show since its inception. The show has branched out to include a number of international versions following a similar format.

Image resolution is the detail an image holds. The term applies to raster digital images, film images, and other types of images. Higher resolution means more image detail.

Image resolution can be measured in various ways. Basically, resolution quantifies how close lines can be to each other and still be visibly resolved. Resolution units can be tied to physical sizes (e.g. lines per mm, lines per inch), to the overall size of a picture (lines per picture height, also known simply as lines, TV lines, or TVL), or to angular subtenant. Line pairs are often used instead of lines; a line pair comprises a dark line and an adjacent light line. A line is either a dark line or a light line. A resolution 10 lines per millimeter means 5 dark lines alternating with 5 light lines, or 5 line pairs per millimeter (5 LP/mm). Photographic lens and film resolution are most often quoted in line pairs per millimeter.
The term resolution is often used for a pixel count in digital imaging, even though American, Japanese, and international standards specify that it should not be so used, at least in the digital camera field.[1][2] An image of N pixels high by M pixels wide can have any resolution less than N lines per picture height, or N TV lines. But when the pixel counts are referred to as resolution, the convention is to describe the pixel resolution with the set of two positive integer numbers, where the first number is the number of pixel columns (width) and the second is the number of pixel rows (height), for example as 7680 by 4320. Another popular convention is to cite resolution as the total number of pixels in the image, typically given as number of megapixels, which can be calculated by multiplying pixel columns by pixel rows and dividing by one million. Other conventions include describing pixels per length unit or pixels per area unit, such as pixels per inch or per square inch. None of these pixel resolutions are true resolutions, but they are widely referred to as such; they serve as upper bounds on image resolution.

According to the same standards, the number of effective pixels that an image sensor or digital camera has is the count of elementary pixel sensors that contribute to the final image, as opposed to the number of total pixels, which includes unused or light-shielded pixels around the edges.

Below is an illustration of how the same image might appear at different pixel resolutions, if the pixels were poorly rendered as sharp squares (normally, a smooth image reconstruction from pixels would be preferred, but for illustration of pixels, the sharp squares make the point better).

"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.
