Red-throated Loon #2

D300, 300mm f/4 + 1.7 tc, tripod
ISO 1000, f/6.7, 1/200 sec
This loon and about 8-10 more were on a small stream on a nature reserve on the SE coast of Iceland. The birds were very small in my viewfinder from the bank of the stream that provided optimal lighting. I found a small section of land that jutted out into the stream where the lighting would be good IF the birds swam to a particular region. I hid in the tall grass and waited. As the sun was setting, the birds swam so close to my position that I got a number of full frame shots and some, like this one, in which the bird did not fit in the frame. I would have alerted the birds to my position if I had made the movements required to remove the teleconverter.
I cropped this version to about 70% of full frame horizontally and 85% vertically for compositional purposes. Noise reduction and
sharpening using Noise Ninja. Exposure, brightness and saturation adjustments using LR and PS3.
What might appear to be a halo around the bird is not because of post-processing. It is natural lighting.
Comments and suggestions most welcome.
