Shooting the quick sunset at the summit of Cadillac Mountain was the reason for much of my dissatisfaction. I was shooting in aperture priority mode, dropped my exposure to two stops underexposed, and forgot to reset it for our harbor cruise the next morning. Translation: all of my shots from the boat were severely underexposed and full of noise when I corrected them in post. Guess I'll have to go back to Maine with new glass and a lesson learned!
