The above image us among a good example of a good photographer. The difference between normal guys and a photographer, is photographer sees beyond others.
Or in some cases photographer imagine things, which one didn't see. These are also called ideas and similiar to a painter ideas come into an image by them. A photographer paints its image using camera whilst a painter uses a brush on a kanvas.
Both of them are called artist.
