In photography, the first and last hour of sunlight during the day is known as the Golden Hour. At those times, when the sun is near the horizon, the light appears softer and warmer, and shadows are longer. “Hour” is used quite loosely, since the length of the warm light varies with cloud cover and latitude.
The photographs in this post were made in the golden hour around sunrise while hikinh on Mount Rubidoux. In landscape photography, the warm glow of the low Sun is considered desirable because of the way it enhances the colors of a scene. Although generally warm, the color palette of the golden hour can vary widely depending on atmospheric conditions. In cinematography, this lighting is called the “magic hour”. The 1978 Terrence Malick film, Days Of Heaven was photographed entirely in golden hour light.
