Sport: Creative Underwater Photography
Photography is the process, activity,
and art of creating still pictures by recording radiation on a
radiation-sensitive medium, such as a photographic film, or electronic
image sensors. Photography uses foremost radiation in the UV, visible
and near-IR spectrum. 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 or plate) or a FPA pixel array sensor
by means of a pin hole or lens in a device known as a camera during a
timed exposure. The result on film or plate is a latent image,
subsequently developed into a visual image (negative or diapositive). An
image on paper base is known as a print. The result on the FPA pixel
array sensor is an electrical charge at each pixel which is
electronically 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.
