This technique is called "Contrast Mask" because it can be used to decrease contrast on photos that has contrast that is too high. It will decrease the level of highlight area and increase the level of low light area.
However, if you have a low contrast photo where most of the photo is of midtone values, then Contrast Masking really is beneficial at all.
