A realistic street photo of a stencil mural on a cracked concrete wall in San Francisco. The mural shows black half-body male silhouettes holding glowing smartphones, controlling people below with puppet strings. The phones are bright and cold, symbolizing Big Tech control and digital manipulation. Torn fragments of tech brand logos and advertising are glued into the wall, faded and weathered. Urban graffiti, paint drips, peeling paper, rough concrete texture. Muted colors: black, gray, beige, rust red, with only the phone screens glowing. Natural daylight, documentary street photography style, realistic, gritty, no illustration, no digital art See more
