Envision a 21 century world where everything is crafted from sand, as if the grains have come to life to form a modern metropolis. Capture this surreal scene with a medium-format camera, using a 50mm lens to emphasize the intricate textures and details of the sand structures. The aperture is set to f/11 to ensure a deep depth of field, keeping the sand buildings, people, cars, and houses in sharp focus from front to back. The shutter speed is set to 1/125s to freeze the gentle movement of the sand particles in the breeze, creating a sense of stillness in this ephemeral world. The lighting is soft and diffused, with a warm color temperature to evoke a sense of wonder and magic. The camera is positioned at a slight Dutch angle, adding a touch of dynamism to the composition, as if the viewer is discovering this fantastical world for the first time.
