"Create a cinematic 4K image, DSLR Canon style, of a crystal-clear lake. Show the lake water with such clarity that the bottom is visible, revealing thousands of colorful gemstones, such as rubies, emeralds, sapphires, and amethysts. The scene should highlight the beauty and richness of the gemstones at the lake's bottom, with light reflecting and refracting through the water to create a stunning visual effect."
