A confident mature man with silver-grey hair

A confident mature man with silver-grey hair and a full white beard posing against a black background. He wears an unbuttoned black-and-white vertical striped shirt that reveals his muscular chest, with the sleeves rolled up, and a black wristwatch. He looks directly at the camera with a slight smile, one hand adjusting his sleeve. Dramatic studio lighting highlighting his features, stylish and strong atmosphere, highly detailed, photorealistic. 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.
