This was a shot in the dark really. I had taken my D90 with me to the first ever Red Bull Flugtag in our area. I kept that camera glued to my eye all morning and day, taking about 400 pics. Every time a Flugtag craft started to get launched of the ramp, I just started snapping away, zoomed as far as I could go. A few of those I decided to turn bracketing on, and try an HDR with a moving craft. It turned out really nice.
