Prompt con parámetros técnicos (fotografía hiperrealista): A hyper-realistic portrait of a very thin, shirtless red-haired painter in his 60s, with a scruffy, unkempt gray-streaked beard and messy, tangled hair. His pale, weathered skin shows veins and bones beneath the surface, etched with deep wrinkles and dark circles under his hollow eyes. His expression is weary yet intense, raw and haunted. His torso is smeared with chaotic paint stains, some glossy and fresh, others cracked and dry. He carries a worn, cracked leather bag filled with old, stained brushes sticking out. In his hand, he grips a vivid, realistic red heart dripping thick paint, the liquid flowing like fresh blood. Behind him rises a massive stone wall carved with detailed cave art and primitive symbols, gritty and textured. Cinematic studio lighting, dramatic shadows, harsh contrast. Ultra-detailed pores, wrinkles, veins, and paint drips. Shot with a Canon EOS R5 + 85mm f/1.2 lens, aperture f/2.0, ISO 200, 1/125 shutter speed. 8K resolution, photorealism, DOF (shallow depth of field), volumetric light, sharp focus on the painter, slightly blurred background for depth.
