Trigger precision: how to achieve the perfect camera shutter synchronization in a bullet-time shot

How to trigger all cameras at the same moment?

  1. Continuous lights
  2. External strobes, speedlights and popup flashes

How to trigger at the right moment?

Having the cameras trigger at the same moment is one thing, but freezing your subject at the exact time you want is something else. Don't you want to capture your subject at the top of a jump? Here's how I do it: Using my favorite wireless trigger, I hold down the button which puts all cameras in stand-by mode, then I release at the right moment to freeze the action. That works well as you can see here: https://www.instagram.com/p/BvE2H8tjGbM/ . In some cases, you might notice a small delay after you release the shutter. Check out the value of the "trigger warmup delay" in Settings / Advanced. Set it to 1ms  to get instant triggering (this might reduce the trigger precision in some cases)

Mirror lockup

If you're using Mirror lockup, here's the right way to get perfect precision:

  1. lock the cameras (full press & release)
  2. arm the cameras (press down for at least 1/2s)
  3. release the button at the exact moment
