WHEN THE SUN GOES DOWN

WE ALL DO

Golden "hour" refers to the period just after sunrise or just before sunset admired for its golden tones not just by photographers. When the Sun is just above the horizon, its rays impact the Earth at a low angle and they have to travel through more of the Earth's atmosphere before they reach the Earth and more of the illumination comes from indirect light from the sky. The lesser light diffusion and its lesser intensity create an environment when people feel the need to slow down, rest, and admire the scenery. 
On their way to the Earth's surface, the rays encounter atmospheric particles such as dust and water droplets, which filter the sunlight, ultimately making it less bright. This process also adds more indirect light to the mix, softening contours and reducing the contrast. The thicker and more pol-luted layer of the atmosphere the sunlight has to pass through breaks the blue and violet wavelengths, allowing more light in the orange and red spectrum to reach Earth. Therefore, the more polluted the atmosphere is the more it decreases the sunlight's color temperature and makes it take on a golden or reddish hue that is admired so much.
