One that you either like or dislike I guess. I was panning with this shot but even though I was not at full zoom I ended up with not much room at either ends of the frame, so I added some canvas to both ends in PS. I know it's usual to have more room for the bird to "fly into", but I'm quite happy that I was able to get it all in frame.
