simply put...

photography is the art of taking photos...

but it can also be scientifically described... as a concept...

photography:  the process or art of producing images of objects on sensitized surfaces by the chemical action of light or of other forms of radiant energy, as x-rays, gamma rays, or cosmic rays.

photography: The art or process of producing images of objects on photosensitive surfaces.

photography: The art, practice, or occupation of taking and printing photographs.

photography: A body of photographs.

photography: The act of taking and printing photographs.

photography: The occupation of taking and printing photographs or making movies.

photography: The science which relates to the action of light on sensitive bodies in the production of pictures, the fixation of images, and the like.

photography: The art or process of producing pictures by this action of light.

but that is just a concept... it is also...

photography: the art of capturing the beauty of life, the act of appreciating 'the moment,' and used as a personal database in one quick snapshot.

photography: art very much like impressionism. You're capturing life as it's happening. A great medium for Creation
of a journal or story.

photography is more than just an exact science... it is an art like any other. one that can not merely be described in concept.. and is that in which can only be explained in the act or viewing of results and process... its all about timing and view point. there is a trick to it... as there is in anything... but it is well worth it.
