This is the same image. I wanted to accentuate the green color of the hillside in the background (Mercer Island). Per the topic, I added just a bit of saturation to the green. I think this breaks up the image nicely, giving a clean break between lake and island, and between island and sky. Also, I added some contrast to the clouds, and applied a noise reduction filter.
Thanks everyone. To be honest, the day started with rain and overcast skies. I had feared that the invitation from my boss (to members of a specific project team) to join him on his boat to watch this practice session would prove fruitless, from a photographers point of view. But the sun came out, the clouds broke, and the practice began. It proved to be a lovely day.
