What is Photojournalism?

In my mind, photojournalism is telling a story using pictures. To become a good photojournalist it is a matter of waiting for the right moment and positioning yourself perfectly to get the right shot. In regular photography, a photographer takes still pictures, one by one. In photojournalism, photojournalists use them to write a story without using words, just pictures. The only difference between a photojournalist and a journalist is the photographs. A journalists uses words and their writing to project a story while a photojournalist uses pictures.
