Conn coast a few weeks ago. Very cooperative subject on a piece of driftwood. Almost full frame.
EOS-1D MarkIII 1000mm (500 + 1.4) 1/250 ISO 400 f/10 tripod
Great preening plover shot, Neil. Another crop possibility might be having the bird a bit more to the right rather than centrally placed but lovely as is too. Great detail, sharpness, exposure. If you were at 1000mm you must have had a 2x TC on? Or were you really at 700mm?
Terrific behavior captured here. You have great details and spot on exposure. Agree on keeping your subject out of the center. I would tone down the brightness of this capture just a tad.
