Focal length portrait comparison grid

Use the following prompt as the common prompt: A hyper-realistic photographic close-up of a woman's face. The model is the same 28-year-old woman, with natural features, realistic facial bone structure, maintaining exactly the same identity, hairstyle, and makeup. The subject faces the camera directly, head kept level, face centered, with a natural relaxed expression, eyes looking straight at the lens. Use a full-frame camera, vertical 3:4 composition, with the subject's head occupying 70% of the frame height, and the camera always at the same height as the subject's eyes. Preserve realistic skin pores, fine textures, natural skin tone variation, and small imperfections; avoid skin smoothing and excessive beautification. Use soft, even natural daylight, maintaining the same lighting direction, intensity, background environment, and color style. Professional portrait photography, high-definition detail, realistic optical imaging quality, without altering the subject's true facial anatomy. Use the following 4 extended prompts to generate a 1x4 large banner image comparing focal lengths: 1. Use a 35mm wide-angle lens, with the camera approximately 0.5 meters from the subject, keeping the subject's head the same size in the frame. Present facial feature relationships according to real close-up photographic perspective rules, with the nose relatively prominent and obvious front-to-back depth in the face. 2. Use a 50mm standard lens, with the camera approximately 0.7 meters from the subject, keeping the subject's head the same size in the frame. Present moderate close-up facial perspective, preserving the natural three-dimensional relationship of the nose bridge, cheekbones, and jaw. 3. Use an 85mm portrait lens, with the camera approximately 1.2 meters from the subject, keeping the subject's head the same size in the frame. Present more natural facial proportions according to real photographic perspective rules, with the nose's relative prominence reduced and softer facial layering. 4.
