+                values cause desaturation on lightened shadows. It is normally

+                saturation boost on shadows – similar to the one you would also 
+                expect in nature if shadows would receive more light.

+                fitting value depending on your specific image; but be aware

+                variations beyond the white point, i.e. above a luminance value 
+                of 100. A negative shift in the white point adjustment slider 
+                allows to bring these values down into the proper range so that

+                transitions between shadows and highlights but might introduce 
+                halos. Lower values will reduce the size of halos but may lead

+                to the extreme shadows and highlights; low values cause strong
