Photograph a 32-year-old East Asian woman rehearsing a brass trumpet in a modest jazz practice room. She wears a charcoal knit shirt and loose cream trousers, standing in relaxed three-quarter profile with both hands correctly operating the valves. Frame from knees upward in a vertical 3:4 composition, using an eye-level 50 mm lens. A tall side window supplies cool afternoon light while one tungsten floor lamp adds a warm edge. Place a blurred piano and folded music stand behind her, with no readable sheet music. Preserve natural skin pores, subtle brass tarnish, knit fibers and worn acoustic panels. Muted slate, amber and ivory palette, documentary editorial realism, quiet concentration rather than performance spectacle. Deliver one finished bitmap photograph; no captions, brands, watermarks, extra fingers, duplicate instruments or unnatural mouthpiece contact.
