Photojournalists create pictures that contribute to the news media, and help communities connect with one other.
Photojournalists must be well informed and knowledgeable about events happening right outside their door.
The situation implied by the images is a fair and accurate representation of the events they depict in both content and tone.
The images combine with other news elements to make facts relatable to the viewer or reader on a cultural level.
Like a writer, a photojournalist is a reporter, but he or she must often make decisions instantly and carry photographic equipment, often while exposed to significant obstacles.
A journalist is a person who collects, writes, or distributes news or other current information.
