High-speed cinematography serves as an excellent tool for investigation of cavitation bubble dynamics on various time scales. We report on methods and results in two cases: The aspherical bubble collapse is studied with up to 100 million frames per second, and the fast motion of many bubbles in an acoustic field is recorded at a picture rate of 2250 per second.
