Here are a couple of close-up shots of an American Avocet from Bolivar Flats as he was walking towards me. The darker colors around his head/neck are breeding plumage. Only minor cropping and no sharpening.
Taken with Canon 1DX and Canon 500mm F4 IS II with 1.4X III teleconverter mounted on Skimmer ground pod with Wimberley II gimbal head
1/1000 sec @ F11, ISO 1600, evaluative metering, +1 exposure compensation (due to bright background)
