How fast does the flash of a camera last? This shot was snapped by my brother-in-law on my phone exactly the moment I snapped a picture on my #nikon5100 . Hence the line through the picture like you use to get on the film slr cameras when your synchronization was off because you didn't have the apersture set at 1/60th of a second.
