Re: High-power LED flash: too good to be true?

They posted a lighting setup diagram where they indicate the flash duration is set to 1/500 second, and the camera shutter speed is also 1/500 second. I don't understand how this is possible since at 1/500 second, the sensor on the 5D Mark II will never be completely open, so how are they evenly exposing the frame with a flash duration of 1/500?
