This is one of those photos that when I look at it I have a strong memory of the moment it was taken. I was on vacation and got up before sunrise to go out with my camera. I stopped at a small village and found my way to the town dock just as this guy was going out to check his lobster traps. I can still feel the mist, smell the salt water, and hear the engine of the boat going by.
They normally don’t look quite this blue. I think it is the lighting that I get at this one place I go to, which comes from sunlight reflected from foliage on the other bank of the stream. It does odd things to the color balance.
