When I stood on the beach and watched this sunset, the red color of the clouds was so saturated - that I couldn't really resolve the details in the clouds when looking at them. Surprisingly, the camera had a a bit more success then the eye, this time. The sky in this picture were left untouched except for global exposure adjustment, which was necessary in order to make it look the way it appeared in reality, with the eyes' dynamic range instead of the sensor's. The saturated teal in the water was exaggerated by the long exposure. Of course, some additional post-processing was applied, but it's pretty minor except for dynamic range compensation.
