Portrait — Side-by-Side Results
Prompt
"Portrait photo with an 85mm lens feel and shallow depth of field: a 20s woman with shoulder-length wavy dark brown hair in a simple oversized gray hoodie and black leggings, holding her phone slightly above eye level for a casual selfie and glancing near the camera with a relaxed half-smile. She’s sitting at a small window table in a cozy neighborhood café with an iced latte and a tote bag on the chair, warm natural window light on her face and soft bokeh of people and plants behind her. Candid, everyday Instagram story vibe—slightly imperfect framing, authentic expression, not editorial or cinematic."
