Appetizing street food photography, horizontal 4:3. A winter street vendor stall with a black iron drum roasting oven: the vendor, an adult woman in a thick padded coat and knitted hat, lifts a roasted sweet potato split open to reveal glistening golden honey-colored flesh, steam curling in the cold air. An unmarked wooden board, a brass scale, and a basket of unroasted purple-skinned sweet potatoes complete the stall; blurred passersby in scarves and falling snow in the background. Warm oven glow against cold blue winter dusk, crisp skin texture, shallow depth of field, no readable text, no logos, no watermark.
