Create a highly realistic, ultra-clear image in a 16:9 aspect ratio, depicting an infinite, perfectly still lake with a mirror-like surface. The lake should be completely smooth, without any ripples, extending towards the horizon to evoke a profound sense of emptiness. The background should feature soft, sparse clouds, enhancing the minimalistic and serene atmosphere. Capture the scene with the Hasselblad H6D-400c, known for its 400-megapixel resolution, ensuring that every detail is captured with extreme clarity. The overall composition should be bright and clear, with an emphasis on open space and simplicity, creating a tranquil, almost ethereal feeling of vast emptiness.
