Meaning of Photography according to Wikipedia
Photography (pronounced
/fәˈtɒɡrәfi/[1]) (from
Greek φωτο and γραφία) is the process, activity and
art of creating still or moving
pictures by recording
radiation on a sensitive medium, such as a
photographic film, or an
electronic sensor.
Light patterns reflected or emitted from objects activate a sensitive chemical or electronic sensor during a timed
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.
The word "photography" comes from the
Greek φώς (
phos) "light" +
γραφίς (
graphis) "stylus", "paintbrush" or
γραφή (
graphê) "representation by means of lines" or "drawing", together meaning "drawing with light." Traditionally, the products of photography have been called
negatives and
photographs, commonly shortened to
photos.
