Photojournalism involves accurately capturing current events in photographs to illustrate news stories. Great photojournalism uses images to tell the story before the text. While maintaining objectivity and integrity, powerful photojournalism engages viewers emotionally and makes them want to learn more about the event. A code of ethics prohibits altering images, as even subtle manipulation can damage credibility. Formal training is often required for photojournalism careers, though some self-taught photographers still succeed. Iconic examples like 9/11 photos continue to impact viewers long after the words are forgotten.
