In order to capture slow-motion footage in which a bullet can actually be seen traveling through the air, a camera has to film at a speed somewhere in the neighborhood of 5,000 frames per second. Given that as a benchmark, what would be the purpose of a camera that manages a whopping 4.5 million fps? In the case of the UK-based Science and Technology Facilities Council (STFC)'s new X-ray camera, it's to obtain three-dimensional images of individual molecules.
