From a couple of weeks ago when there were still a bit of leaves in the trees to reflect in the water, because as you can see the male Wood Duck needs all the help it can to make images colourful.
Canon 7D + 500mm f/4 II + 1.4TC, manual exposure, evaluative metering, 1/200s., f/5.6, ISO 800, natural light, handheld, about 85% FF, the flanks darkened, and the white "chinstrap" also toned down to reveal more detail. Duck attracted closer with cracked corn.
