2/15/2011: Red-shouldered Hawk (im)

It is often windy at Merritt Island NWR, and that can make digiscoping, with its particularly high effective magnifications, very difficult. This shot from late afternoon when the wind was well up, and the bird was 150 yards across a water channel, shows the effects. Being in tree that caught the wind and bounded around even more did not help. Even though the shutter speed was a 500th of a second, The shot is not critically sharp, and required extra processing for sharpness and clarity to approach acceptable. Still, it is a nice bird: an immature Red-shouldered hawk of the light Florida variety. 

Increasing magnification only makes matters worse:

In this shot you can see a clear indication of the problem in the eye-light: notice that it is a vertical line, not a dot. That means that the bird was in motion when the shutter opened…or in this case that the whole tree was in motion.

Still…it is a nice bird.

Canon SD4000IS behind the 15-56x Vario Eyepiece on the ZEISS DiaScope 65FL spotting scope. 1) 2700mm equivalent field of view, 1/500th @ ISO 125, 2) 4000mm equivalent field of view, 1/320th @ ISO 125.

My standard processing in Lightroom for clarity and sharpness, but then both were selectively sharpened, clarified, and contrast boosted around the head and eye using the selective brush tool. The whole image got Fill-light, Blackpoint adjustment, and Contrast boost…and then I backed off the Vibrance slightly to tame the yellow highlights. And still…it is a nice bird is about all I can say.
