It is approximately 80%, which is a realistic maximum for the clear Rayleigh sky during day time. The video thus begins when the sun is slightly above the horizon and at an azimuth of 120°. The sky is highly polarized in the effective North-Zenith-South plane. This is slightly offset because the sun's azimuth is not due East.
[3] [10]: 3:57 "I don't think the engineers or anybody at Microsoft had any idea it would have the success it had," he said. [10]: 4:40 After the rights to the photograph were bought by Microsoft, it was renamed Bliss and was chosen as the default wallpaper of the Luna visual style, [2] [26] the default graphical user interface of Windows XP.

Rayleigh scattering causes the blue color of the daytime sky and the reddening of the Sun at sunset. Rayleigh scattering (/ ˈ r eɪ l i / RAY-lee) is the scattering or deflection of light, or other electromagnetic radiation, by particles with a size much smaller than the wavelength of the radiation.
The color of light from the sky is a result of Rayleigh scattering of sunlight, which results in a perceived blue color. On a sunny day, Rayleigh scattering gives the sky a blue gradient, darkest around the zenith and brightest near the horizon.
In probability theory and statistics, the Rayleigh distribution is a continuous probability distribution for nonnegative-valued random variables. Up to rescaling, it coincides with the chi distribution with two degrees of freedom .
The Horizon universe was adapted into a comic book in 2020, with the release of Horizon Zero Dawn: The Sunhawk. [11] The comic book bridges the gap between Horizon Zero Dawn and Forbidden West. A second comic set during the events of the first game, called Horizon Zero Dawn: Liberation, was released in 2021. [12]
The result, θ = 4.56/D, with D in inches and θ in arcseconds, is slightly narrower than calculated with the Rayleigh criterion. A calculation using Airy discs as point spread function shows that at Dawes' limit there is a 5% dip between the two maxima, whereas at Rayleigh's criterion there is a 26.3% dip. [3]
The above image shows the degree to which Rayleigh scattering scatters blue light more intensely than red light. The scattering curve shown is calculated for sunlight passing vertically through the atmosphere and is based on Bucholtz, Anthony (1995).
