Shot in Nisqually National Wildlife Refuge, while looking for extremely elusive birds. This volunteer posed repeatedly, nodding his head like Wall-E, and let me get within two feet of him.
Canon Rebel with 300mm prime lens; f/4.0 at 1/800 shutter speed, ISO 200.
By shooting with the lens wide open, I was able to capture its head with good detail and both the rest of the boring fence and the bog behind it disappeared. I'd have like his tail in focus, too, but with this lens, I don't think that was going to happen anyway, unless I moved back to six feet.
The histogram, surprisingly, isn't overloaded at the black and white ends: the bulk of the pixels fall nicely in the middle of the scale, with lots of detail in the fence and the dragonfly's fore-end. There's little true white in the photo anyway: reflection on his eye and a bit of the wood grain.
