Tonight's photo was a little harder to get than my average photo. I tried something still kinda new to me. I tried to rotate the camera during a long-ish BULB exposure and use rear-curtain flash sync to freeze the subject.
You see, the flash will fire at the very LAST instant of the exposure, but there was a slight delay from when I release my finger from the shutter button and when the exposure stops, and the flash fires. It was no problem to make the BULB exposure with the rotation and end up properly composed, just hard to time the end of the exposure with when I wanted the action to be stopped.
An idea came to mind. I thought how I could do the exposure and composition with my right hand, and hand hold my pocket wizard in my left hand and fire the flashes manually when I wanted. This was the ticket. It worked quite well. Brian and I were finally stoked on this one after he had landed it prolly more than 10 times... I said to him, "Good thing you aren't jumping down 12 stairs of something...!" we had a good laugh.
strobist: sb-900 behind me to the left with Wide Angle flap down at 1/8 power. sb-900 to camera right about 3 o'clock at 50mm and 1/8 power. Fired MANUALLY with pocket wizard plus II's.
