An Hourglass With Sand Flowing From The Upper Chamber To The Lower Chamber Against A Dark Background. Stock Photography

An hourglass with sand flowing from the upper chamber to the lower chamber against a dark background. The hourglass should have a classic design with a narrow waist and bulbous ends, and the sand inside should be fine and light-colored, creating a soft contrast with the dark background. The lighting should highlight the smooth flow of sand and give a sense of time passing in a serene yet inevitable manner.
