Learning More About PhotographyPhotography is the art and process of creating still life pictures by recording radiation on a sensitive medium. This is photographic film, or electronic imaging sensors that can capture the picture. Light is usually used instead of radiation in most cases of photography. When the light is reflected from the objects that are being captured, the objects form a real image on a light sensitive film or plate inside the camera using a timed exposure. This image can then be developed into a visual image for many purposes.History of PhotographyPhotography was initially invented in the 19th century. It created a whole new way to capture images instead of using paintings and sculptures. The usable process of photography dates back to the 1820’s however when chemical photography was thought of. The first photoetching was produced in 1822 by Nicephore Niepce. He and Louis Daguerre invented a new way to take pictures quicker using silver and chalk. The first ever photo taken of a person was taken in 1839 with the new invention. Negative images were created in 1840 by a man named Talbot; his print is the oldest known negative in existence to this day. The blueprint was developed by John Herschel in 1819 by the use of silver halides. His discovery allowed pictures to be permanent, and made the first glass negative in 1839.The wet plate collodion process of photography was used widely between 1852 and the late 1860’s before the dry plate was introduced. It involved a positive image on glass, positive image on metal, and then the negative that was printed on salt paper. Advancements in photography continued to expand throughout the 19th century. The plates were replaced with film which is used today in 1884. Colors were introduced in 1908 by Gabriel Lippmann who won the Nobel Laureate in Physics for this creation.Uses of PhotographyA lot of people gained interest in photography for many reasons since it has been introduced. One of the biggest uses was for scientists to record and study movements in space, animals, and humans. Artists also gained interest in photography because they like to capture reality, and also turn reality into fantasy by distorting the images that they take creating art from these images for display. The military also uses photography for surveillance and date storage. Everyday people use photography to capture special moments in life, and to preserve those times in the pictures as well as a source for entertainment.Production of PhotographyAmateur production of photography is when photography is done in a not for profit way, and as a hobby.
