If I create a selection ( example the foreground of a landscape shot ) and I want to apply a curve adjustment to that selection is there a method if softening the edge of the selection line? If I pull a curve to boost the contrast there is a harsh cut off line line separating the selected area and the non selected area.It means I have to be perfect with my selection but I would prefer the adjustment to blend in or feather ( not sure of the right word ) either side of the selection line
