//TONEMAP: Completely post processes the colours for more natural contrast and saturation (leave SKYRIM config gamma at 1.0, use gamma below to adjust for your monitor 
#define Gamma 1.24             // higher values give a darker and more saturated colour band
#define Exposure 0.095         // simulates exposure: higher values dramatically increase strength of bright parts of the image, used here to balance the overall loss of gamma brightness and to increase the overall contrast
#define Saturation -0.03      // strength of the colour band, lowered here to balance the excessive saturation caused by high gamma whilst retaining high and natural contrast
