The special characteristics of light at sunset—first the “golden hour,” followed by the “blue hour”—are well known to all serious landscape photographers. Indeed, the quality of the light and the emotional resonance of the views of this good earth as sunset commences, and for a while post-sunset, is clear to all romantic observers of every persuasion.
What is less well-known is that sunrise duplicates the same wonderful sequence, but in reverse. So shortly after dawn there is a blue period, followed by a time of golden lighting, and then daytime commences. For astronomical reasons, morning blues and golden hues tend to be shorter in duration than those in the evening—but they are no less potent and emotionally heart warming.
