Blood red, a photo from Liege, Wallonia

Photographer's Note

Why the sky coloured is in red? With the rising or laying down sun, the sun is low on the horizon. The rays of the sun cross the atmosphere according to an angle much smaller at midday for example. The thickness of the atmosphere that they cross before reaching us is thus more important. When for example the angle with the top of the horizon is only of 4 degrees, the thickness to be crossed is 12 times more important than that which they cross at midday. The fraction of the most dispersed light is that the short wavelengths (blue); only longest (reds) reach the observer.
