Studio-quality editorial portrait of a poised young woman

Studio-quality editorial portrait of a poised young woman in an all-white outfit: crisp white button-down shirt with sleeves casually rolled to the forearms, slightly open collar, tucked into tailored white trousers. She leans with one hand on a vintage leather-topped wooden desk with brass studs, the other relaxed by her side, conveying calm confidence. Warm ambient lighting from an interior library or study casts soft highlights; a large window behind her shows evening city bokeh lights. Background includes a bookshelf with globes, books and framed art, and a leather chair, softly out of focus. Hair styled in a neat updo, subtle natural makeup, gold hoop earrings and a wristwatch add elegant accessories. Cinematic, shallow depth of field, 50mm, wide aperture for smooth bokeh, rich warm color grading, soft film-like grain, high-resolution detailed skin texture and fabric, balanced contrast, flattering soft shadows, editorial fashion photography composition, three-quarter length, eye-level perspective, rule-of-thirds framing. Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
