Porto Seguro Palm Leaves: Tranquil Monochrome Silhouette

Create a high-contrast black and white silhouette of layered palm leaves in the foreground against a calm Porto Seguro shoreline. The leaves should be bold, crisp, and curving, forming intricate shapes with deep blacks and soft grays. In the distance, a tranquil sea meets a pale horizon beneath a bright, luminous sky. Emphasize negative space with a minimal composition that conveys tropical tranquility. Use cinematic lighting with the light source from the upper left to cast long shadows on the fronds. Add a subtle film grain texture to enhance the monochrome feel. 16:9 aspect ratio, photorealistic silhouette style.
