Photojournalism is a medium that uses photography to convey factual information and reports on real events. It aims to inform audiences through images that reveal details about people, places, and situations. A typical day for a staff photojournalist involves shooting multiple assignments, selecting the best photos to tell each story, and providing captions to accompany the images for publication. Photojournalists are expected to have both photography and reporting skills to effectively communicate newsworthy information visually.
