The colors of the sea and the poetry of physics 4

As a photographer, I have been fascinated by the constantly changing, often very intense or pastel colors of the sea and the sky for 40 years. As a physicist, I often think about how these colors come about. This knowledge lets me take a closer look and discover nuances that I would otherwise not have seen and could not capture in the photo. Many photos in this series were taken with a 300 mm telephoto lens. They only show a small section of the horizon that is particularly interesting in terms of color. With regard to the colors, the photos have not been edited afterwards.
Only near the horizon was the sky colored redby the sunset; further up it was still bright blue. In the red areas of the picture, the water surface is smooth, i.e. almost horizontal. There the red parts of the sky close to the horizon are reflected. In the blue areas the wind made small waves. We look at the wave surfaces inclined towards us, which reflect the blue parts of the sky near the zenith in the eye or camera.
