Moody Gym Portrait with Dumbbells.

"A realistic photo of a young man in a dimly lit commercial gym, standing facing the camera and holding a 12.5 kg rubber dumbbell in each hand, arms relaxed at his sides. He has short, voluminous dark curly hair with a few strands falling on his forehead, a neatly trimmed short beard and mustache, and a calm, slightly serious expression. He wears a fitted white ribbed tank top, light cream waffle-textured shorts, a silver chain necklace with a round pendant, a small stud earring, and a thin bracelet on his wrist. Moody cinematic lighting with a cool blue spotlight beam coming from above, dark black ceiling, and blurred gym equipment, machines, and weight racks in the background. Dark gym flooring, shallow depth of field, high contrast, sharp focus on the subject, 4:5 portrait aspect ratio, shot on a smartphone, natural skin texture, realistic muscle definition." 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.
