Serene Black and White Duck on Calm San Luis Potosí Waters

Black and white photograph of a duck gliding across glassy, calm water. The scene is set along a tranquil stretch of water in San Luis Potosí, Mexico, with distant silhouettes of colonial buildings and soft hills on the horizon. The water acts as a near-perfect mirror, reflecting the duck and a pale, overcast sky. High-contrast grayscale with subtle film grain to evoke timeless mono photography. Emphasize the texture of the duck's feathers and the ripples trailing behind, and the serene mood of the moment.
