Weird Wacky And Unexplainable Black & White Photos

Photography is the art, science, and practice of creating pictures by recordingradiation on a radiation-sensitive medium, such as a photographic film, or electronic image sensors. Photography uses foremost radiation in the UV, visible and near-IRspectrum. For common purposes the term light is used instead of radiation. Light reflected or emitted from objects form a real image on a light sensitive area (film orplate) or a FPA pixel array sensor by means of a pin hole or lens in a camera during a timed exposure. The result on film or plate is a latent image, which is developed into a visual image (negative or diapositive). An image on a paper base is known as a print. The result on an FPA pixel array sensor is an electrical charge at each pixel which iselectronically processed and stored in a computer (raster)-image file for subsequent display or processing. Photography has many uses for business, science, manufacturing (f.i. Photolithography), art, and recreational purposes.
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. The word photography is based on the Greek φῶς (photos) “light” and γραφή(graphé) “representation by means of lines” or “drawing”, together meaning “drawing with light”.
