Shutter Speed or Frame Rate?


Here’s an old-ish video that’s been making the rounds again lately (viral videos are like viruses — they don’t go away very easily). Titled “Camera shutter speed synchronized with helicopter blade frequency,” it shows what can happen when your camera is synchronized with the RPM of a helicopter’s rotor blades. The resulting footage makes the helicopter look as though it’s just floating in the air!

Photographer Chase Jarvis shared the video today and quizzed his readers on the cause of the phenomenon. More specifically, he asked whether the effect is due to shutter speed, as the title claims, or frame rate.
