Raising the turbidity coefficient in sunset situations will darken the sky. Remember that you can also
alter the EV of the camera in these cases, which can create an interesting sky:
Turbidity Coef. 0.0, EV=15 Turbidity Coef. 0.1, EV=15 Turbidity Coef. 0.1, EV=12
Wavelength Exponent: Defines the average size of the particles in the atmosphere. The particle size influences which
wavelengths of light are absorbed and which are scattered. Higher values than the default will increase
the saturation of the sky, until gradually it turns first green and then orange:
Wavelength Exp. 1.2 Wavelength Exp. 5.0 Wavelength Exp. 10.0
Reflectance: Refers to the albedo of the aerosols, or the rate of energy scattered and absorbed by the aerosols.
Scattering Asymmetry: This factor controls the anisotropy of the particles, that is, in which direction most of the light will be
scattered. Positive values will produce a halo effect around the sun, brightening the area around it:
Scattering Asym. -0.7 Scattering Asym. 0.0 Scattering Asym. 0.7
Ozone: the amount of ozone gas in the atmosphere, measured in the centimeter-height of a column of
atmosphere. The default value is 0.4.
Water: The amount of water vapor in the atmosphere. It is measured in centimeters, in the same way as ozone.
