Have you ever wondered how a DSLR camera's shutter works when a photograph is snapped? Thanks to YouTube's The Slow Mo Guys, you can wonder no more.
Using a Phantom Flex high-speed digital camera, The Slow Mo Guys’ Gavin Free was able to capture the movements of his Canon 7D’s mechanical shutter at a whopping 10,000 frames per second, revealing what actually happens when the camera takes a picture.
Free compared what happens to the shutter during exposures of various shutter speeds -- from 1/8000th of a second to 1/1000th. The movement is so incredibly quick, it'd be impossible to note the differences with the naked eye.
