Photography is the process, activity and art of creating still or moving pictures by recording radiation on a sensitive medium, such as film, or an electronic sensor. Light patterns reflected or emitted from objects activate a sensitive chemical or electronic sensor during a time exposure, usually through a photographic lens in a device known as a camera that also stores the resulting information chemically or electronically. Photography has many uses for business, science, art and pleasure.
Photography is so much part of life today. The average person in the United States may encounter more than 100 camera images a day. Photographs preserve persona lmemories like family snapshots and inform us of public events. They provide a means of identification, glamorization, views of far places even from earth, microscopic organisms and others.
Photography, coming from the Greek awto and ypapia is the process, activity and art of creating still or moving pictures by recording radiation on a sensitive medium, such as film, or an electronic sensor.
