The Blue Hour

The blue hour is the period shortly before sunrise and after sunset when the sky takes on a deep, rich shade of blue. This happens because the sun is just below the horizon, scattering shorter blue wavelengths across the sky. During this time, natural light is softer and more diffuse, creating a tranquil and aesthetically appealing atmosphere, often favored by photographers for its unique color and mood. The duration of the blue hour varies with latitude and season but generally lasts about 20 to 40 minutes, offering a fleeting window of optimal natural lighting.
