I was looking thru some old photographs and found this three that I saw as a great illustration of what I like to say about photographing sunset: it is not over until it is pitch black. All three photos were made a top of Hurricane Hill at different times.
The sky was clear. The evening started with sun slowly setting behind mountain peaks. The streaks of sunshine were breaking thru mountain tops, highlighting mist rising from the bottom of valleys.
Once the last light of sun vanished the valleys were filled with blue cool tones of shade, while the sky was still deep orange. A few minutes after the moon rose just where the sun disappeared.
Later when it got so dark, you could barely see anything deer started gathering at the top against last warm tones of sunset on the horizon.
