White-capped Albatross

I was so focused on tracking this bird from the pitching boat that I didn't notice the cloud formations behind it. It was only after I put the file into the computer that I realized how different it was from a standard, blue sky image. I can't stand those stupid background swaps which many lazy/unethical 'photographers' employ, so it felt great to achieve this result in-camera.
