Photography Memes just shared this 14-second video that will make your face cringe and your heart skip a beat:
The photographer set his camera down on the rail above stairs while setting up for a shoot. Upon opening up his collapsible reflector, he accidentally gives the camera a bump and sends it tumbling and shattering down the stairs.
