In photography, the golden hour or magic hour, especially in cinematography is the first and last hour of sunlight during the day when a specific photographic effect is achieved due to the quality of the light. Typically, lighting is softer (more diffuse) and warmer in hue. Shadows are relatively non-existent if the sun is below the horizon.
When the sun is near or below the horizon, sunlight travels through more of the atmosphere, reducing the intensity of the direct light, so that more of the illumination comes from indirect light from the sky (Thomas 1973, 9–13), reducing the lighting ratio. More blue light is scattered, so if the sun is present, its light appears more reddish. In addition, the sun's small angle with the horizon produces longer shadows.
