Composition and viewpoint are two elements of a photograph or painting that shows off the photographer’s or artist’s “art“. Most people look at objects or scenes from their usual vantage point i.e. the level of their eyes from their standing position. A photographer seeks to make us see the world, that same world everybody else sees, in a new way.
We compose by cropping out or including certain elements in the picture. Again this is how we show that conventional world we all know in our unique way, by eliminating elements without which the picture looks new or including elements that distinguishes this view from again the view most of us see when in a locale. Art is to a large extent the artist’s judgement of what is essential in a picture.
A picture therefore is not the real world but the world as created by the artist’s eye. It is reality only in its origin for the artist re-creates reality in his or her own way. The artist represents reality, does not simply reflect it.
For how can we reflect the vastness of the universe within our finite selves? Artists hint at this infinity by showing that vast, unspeakable Whole in something conspicuously small. As Blake would have it, Oh, but
“To see a World in a Grain of Sand
And a Heaven in a Wild Flower,
Hold Infinity in the palm of your hand
And Eternity in an hour.”
