Summer Dusk In An Open Field

The summer sun bakes the bristling little animals and long stalks of grain until they all become golden and filled with the fruit of the earth. You sit, overseeing your grand garden, pondering the nature of existence as the sun sets and the bountiful flavors of dinner begin to waft through the kitchen window, filling your nose with a thickness that only the most fortunate people on earth are able to indulge. Dusk is the beginning of darkness in the evening, and occurs after twilight, when the sky generally remains bright and blue. Civil dusk is when the earth has rotated enough that the center of the sun is at 6° below the local horizon. This marks the end of the evening civil twilight, the point where artificial illumination is required to read outside. It can be confused with sunset, which is the point at which the earth has rotated enough, that the sun is no longer visible from the local horizon. Twilight is the time between dawn and sunrise or between sunset and dusk, during which sunlight scattering in the upper atmosphere illuminates the lower atmosphere, and the surface of the earth is neither completely lit nor completely dark. The sun itself is not directly visible because it is below the horizon. Owing to the distinctive quality of the ambient light at this time, twilight has long been popular with photographers and painters, who refer to it as the "blue hour", after the French expression l'heure bleue. Twilight is technically defined as the period between sunset and sunrise during which there is natural light provided by the upper atmosphere, which receives direct sunlight and scatters part of it towards the earth's surface.
