Create a 4:5 vertical monochrome jazz singer portrait. A middle-aged Chinese female jazz singer stands on the stage of a small jazz club, wearing a black suit and white silk scarf, holding a vintage silver microphone, eyes closed while singing. The image is black-and-white photography; the background contains a blurred double-bass silhouette, round stage lights, and smoke, but no readable signboard. Composition from half-body to waist, microphone in the left foreground, the singer’s face shaped by side stage light, quiet and powerful emotion. Real high-ISO black-and-white film feel, natural grain, strong shadow detail. 85mm lens, realistic proportions, natural hands and microphone. No readable text, logo, watermark, brand, club name, or poster anywhere.
