After a visit to Apple's Genius Bar in Reston, I walked on down to the ice skating rink in the Town Center. Watching the skaters, I wanted to get a shot showing movement. If I was lucky, I’d get skaters blurring, somewhat like ghosts.
Well, the brightness of the ice was so great that it wasn’t possible to shoot at a slow speed (to get the blur) without greatly overexposing.
This image is essentially out of the camera, taken while I fiddling with the aperture and speed and ISO and what not. Call it a lucky shot.
