Photojournalism tells stories through photographs alone. It began in the mid-19th century with war photography and has since expanded to other newsworthy events. How audiences interpret photojournalism depends on their background knowledge and ability to decode symbolic meanings in photos. Effective photojournalism uses techniques like shot angles, types, and color schemes to convey emotion and perspective without words. Important photojournalists like Marilyn Silverstone used these techniques to capture raw, real scenes and advance the field despite challenges as a woman.
