high values decrease contrast, Low Values Increase Contrast - Special Kind of Power function (see PDF)
This special Kind of power work so: It divide the input in Above 0.5 or mean and Below 0.5 or mean. Then each part is consider as in a range 0-1 and the Power applied to Lower Part is the Inverse of the Power applied to higher part. It is very useful to Increase values above 0.5/mean and decrease the values below this value. Look PDF for a graph of this function.
