I made this image at Lac le Jeune near Kamloops, British Columbia in the summer of 2010. Its been on my list to process for a while. Loons are very difficult subjects with which to nail exposure. If you try and expose for the head, the whites on the body will be blown and if you try to keep the whites well exposed, the head will be very dark and you'll have no feather detail.
Common Loon - 1D4, 800, f/8, 1/1000s, ISO 400
