Super High Speed Footage Of A 60D Exposure Cycle

Our buddy Destin from Smarter Every Day is about to have a new baby, but seconds before rushing to the hospital, he shares a neat slo-mo (or high-speed, depending on your take) video of a Canon 60D shutter going through the a full exposure cycle.

You can see the four stages of the exposure:

  • The mirror flips
  • The first curtain goes down to expose the sensor
  • Second curtain covers the sensor to end the exposure
  • And finally the mirror jumps back up

Now, here is a question for extra credit, can you calculate the exposure time?

Congrats Destin for your new baby!
