Just to be certain, when you loaded the premade Gamma curve you were sure to select "Correction Value INPUT" correct? One of Dominic's or JAVS curves should leave you reasonably satisfied...they each have several curves so be sure to load a few and keep trying them. Be certain to read thoroughly my Custom Curves Quick DIY
