black and white, gritty portrait

A black and white, gritty portrait of a man with a beard and messy hair, looking intensely to the right. He is wearing a dark, open-collared shirt and is leaning on a railing or surface with his forearms. He has a silver ring and bracelet on his left hand. A stylish sunglasses. The background is dark and out of focus, suggesting an urban or somewhat rugged setting. The mood is serious and contemplative. 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.
