smooth vignette gradient.

Create an image of a stylish man in a plain camel-tan crewneck knit sweater and glossy black round-frame sunglasses, chest-up upward portrait, shoulders relaxed, slight lean toward camera-left, head turned about 20° to 30° to the left with a subtle upward tilt, gaze off-camera to the side, naturally styled hair, well-groomed appearance, composed confident "aura" calm

set a seamless warm caramel-to-deep chocolate brown studio backdrop with smooth vignette gradient falloff, brighter behind the head, darker at the edges

light with cinematic studio lighting: strong soft key at 45° camera-right slightly above eye level, minimal fill to keep the shadow side rich, subtle rim light camera-left for separation on the hair and shoulder, add clean specular highlights on the lenses and frame

use a refined monochromatic palette of camel, caramel, and dark chocolate brown with natural warm skin tones

shoot at eye level on a full-frame camera, 85mm lens, f/2.2, crisp knit and skin texture detail, hair texture, shallow depth of field, comfortable headroom, balanced negative space.

4:5 aspect ratio.
