Ultra-realistic lifestyle portrait of a young adult woman with long, wavy black hair parted in the middle, warm light-tan skin, soft feminine facial features, and natural makeup. She is looking directly at the camera with a relaxed, confident expression and a subtle smile. She is wearing a minimal black triangle bikini with white trim and ultra-thin straps. She is reclining on a modern beige sofa, one arm resting casually on the backrest while her torso is slightly angled toward the camera. Medium close-up framing from head to upper thighs. Bright contemporary apartment interior with a blurred open kitchen in the background. Soft natural daylight entering from a large window, creating flattering highlights and gentle shadows. Shallow depth of field, creamy bokeh, 50mm lens, f/1.8, editorial fashion photography, highly detailed skin texture, realistic lighting, HDR, ultra-photorealistic, 8K resolution, natural color grading, premium DSLR quality.
