Photorealistic Candid Street Portrait with Extreme Shallow DOF

A highly detailed prompt for generating a photorealistic, candid street-fashion portrait. The core intent is to achieve extreme shallow depth of field, keeping a single subject tack-sharp in the mid-ground while rendering a moving crowd and the city background as soft blur/bokeh. It specifies composition, lighting (cinematic soft contrast), and critical camera optics (telephoto lens, wide aperture). Via YouMind OpenLab prompt library (MIT).
