On The Go

On The Go - 1D4, 800, f/6.3, 1/2500s, ISO 1600, flash fired
Its been a while since I posted an Avian image so I went through my archives of unprocessed images to find something interesting.  Back in 2010, I made this image of a Red-naped Sapsucker on a trip to Kamloops, British Columbia.  For those who have tried to capture these guys, you know how fast they move so my technique to make this image was just to pre-focus on the nest entrance and stand ready.  When he poked his head out and looked like he was about to fly off, I would release the shutter and fire off a few shots.  This is one of the rare times where I found 10 FPS shooting rate to be useful.  One might wonder why I would use ISO 1600 and flash for an image made during daytime.  The biggest reason for this is the required shutter speed to capture this guy.  After experimentation I found that I needed at least 1/1600s, but preferably 1/2500s to freeze the motion.  Also the nest was in the shade so flash was required to add some fill light.

Nice capture!
I'd be amazed if you said flash recycled that fast... :P

Thanks Mahasen. Since the flash was powered down (somewhere around 1/4 power) and I was using an external battery pack the flash actually cycles very quickly though not quite enough to satisfy 10 FPS, probably closer to about 3 FPS.
