If you see a reporter with a camera, she probably works in the field of photojournalism, the presentation of news and current events visually, using images instead of words.
The word photojournalism was coined in the mid-20th century and refers to a cross between journalism and photography. A photographer whose interest lies in reporting, telling true stories about current events by taking pictures of them, will enjoy photojournalism. While a print journalist might interview people and write a story about a war, a photojournalist will try to capture images of the war and the people and places affected by it.
