Maintain the exact facial structure, bone features, skin tone, eye shape, and identity of the person from the uploaded reference photo without alteration. An intimate fine-art black-and-white portrait of the subject seated next to a textured concrete wall indoors. A sharp, diagonal beam of natural sunlight slices through a nearby window, casting hard geometric light and a clear, defined shadow of the subject's profile onto the wall behind them. The subject wears a heavy black textured ribbed knit sweater, seated in three-quarter profile looking thoughtfully to the side. Rich silver-gelatin monochrome tones, velvety crushed shadows, razor-sharp focus on skin texture, loose flyaway hair strands catching highlight edges, Ilford HP5 Plus film aesthetic, 50mm f/1.8 lens.
