Civil Twilight

According to the National Weather Service, civil twilight “begins in the morning, or ends in the evening, when the geometric center of the sun is 6 degrees below the horizon.” I learned this phrase from Denise Wilton’s Walknotes and was immediately smitten by it. When, in early April, it was announced that the final project for my photography class would be a subject of my own choosing, “Civil Twilight” was the immediate frontrunner.
