Shutter Speed & Strobes

One concept that takes many photo students awhile to grasp is that when using strobes your shutter speed controls the ambient light. The only difference between these two images is that the one on the left is shot at 1/20s and the one on the right is shot at 1/250s.

I wish I had moved my key light around a little more camera left to get some catch light in his eyes, but tomorrow is another day in the world of newspapers.
