The TonemapDrago type exposes the following members.
Value for bias function in [0, 1] range. Values from 0.7 to 0.9 usually give best results, default value is 0.85.
Positive value for gamma correction. Gamma value of 1.0 implies no correction, gamma equal to 2.2f is suitable for most displays.(Inherited from Tonemap.)
Pointer to the unmanaged object(Inherited from UnmanagedObject.)
Positive saturation enhancement value. 1.0 preserves saturation, values greater than 1 increase saturation and values less than 1 decrease it.
