Old national geographic grainy photography, fined grain photo : Render an image of a smooth river stone, polished by the flow of water and glowing with a soft, blue light. Intricate, natural patterns are etched into the stone’s surface, resembling ancient symbols or constellations. The stone is held in a cupped hand, with water droplets clinging to the fingers, glowing faintly as they roll off the stone. The background is blurred into a misty riverside setting, with the sound of flowing water and the rustling of leaves adding to the serene, magical feeling of the scene.
