This is a pano crop because it comes from one of those shots where the bird popped up out of nowhere and there wasn't time to arrange everything perfectly without sacrificing a chance at a head shot. I picked 16x9 to get rid of the empty space above the bird that resulted from his being rather low in frame (again, no time to set it up exactly as I wanted it) and to emphasize that long and colourful bill. I had the 1.4 converter on the lens at the time, and I can't really remember why - I might have switched from a songbird spot over to where the toucans liked to go - but that extra length more or less limited me to close-ups.
The editing, post DPP conversion, involved some bill clean-up, shadow/highlight adjustment, and a bit of added warmth to compensate for the fill flash.
