Quick Post: X-sync

The other day I was playing with the idea of using my Dynalites to sync up with my camera to something greater than the 1/250 limit. I know that at full-power, the light duration is 1/64,000. The camera's fastest shutter speed is 1/8000, so theoretically the camera is slow enough to capture that glimpse of light.

I needed very shallow depth-of-field to blur out the busy bookshelf and keep focus on the subjects. I used a 50mm lens at f/1.6 and 1/6400 (at 1/8000 a vignette is more apparent), ISO100. I think it worked great - just can't wait to use it outdoors to kill the ambient or do some motion freeze with the power of Dynalite strobes.
