Clicking with the middle (50% grey) eyedropper on the blue-ish hills in the distance tells Photoshop to white-balance to the opposite of blue-ish, which is this sepia, and then clicking with the white eyedropper in the brightest area, which is the cloud centre-left top. It's not quite the same as using a sepia filter or colorize.
If you try to find a more usual mid-grey you'll get a more accurate colour balance. There are auto-mask methods for finding the 50% level in a shot, but it's usually more fun to click around with the eye droppers at random to see what happens.
This is almost a photo magazine shot. You'd need an even longer exposure on the waves to make them even wispier, an even wider lens, and ideally you'd also need to take it at sunrise or sunset to make everything look dramatically pink or orange. This should be followed by even more dramatic Photoshop colour enhancement, until you get something that looks like a rather poetic episode of Star Trek, where the sky is bright pink and misty and the clouds are made of hydrogen.
I'm not suggesting any of these are a good thing, but it's the kind of style the mags seem happy to print rather a lot of.
I'd rather:
which is a slightly less familiar crop, but I think it still captures some of the essence of the scene.
