Photorealistic candid photograph of an elderly sailor on a small fishing boat. Weathered skin, faded sailor tattoos, calmly adjusting a net while his dog sits on the deck. Shot like a 35mm film photograph, 50mm lens, soft coastal daylight, shallow depth of field, subtle film grain. Honest and unposed — real skin texture, no glamorization.
