Attention to things I should have done differently:
At 75 yards, I was too far away, even with 400mm. It was 8:41 AM on August 17, 2010. Elevation 8700'. Sun on the back of my shoulders. That was too late in the morning, as the sun was high enough to cast harsh shadows. I used evaluative metering, which produced a compromise exposure on both sky and bird. Even then, it was only because of the exposure flexibility of the RAW file that I was able to bring up the shadows under the body to bring back enough detail to the underside, carried prey and talons. The goal for me is always to avoid blocking up the shadows. Wide open aperture of this lens was f/5.6. I was at ISO 320. This allowed 1/2500s. It's not completely clear if I had the DOF plane placed on the bird. It would have been better to have been at shutter speed 1/5000s, which would have been reached with ISO 640 or ISO 800. The image would have been sharper, at the cost of a little extra noise. I did remove noise/grain selectively from the sky with Dfine2.
The prey was a Wyoming (Richardson's) Groundsquirrel. |
