Photojournalism involves capturing truthful images that tell news stories visually rather than through words. It has several key elements, including timeliness, objectivity, and narrative. There are different branches of photojournalism such as documentary photography, social documentary photography, street photography, and celebrity photography. A photojournalist's role is to visually report facts and serve the public through images that show what people are doing and what is happening in an honest, unposed manner. Photojournalists have an ethical responsibility in deciding what images to publish and respecting subjects' privacy.
