duplicate the layer twice and the middle layer is a color balance where i do +10 blue to negate any yellow, the top layer i do screen anywhere from 20%-40% or even higher if the picture is super dark, merge layers, make a new layer and do auto curves, merge again, then i run azurite's glowy icon action and turn the opacity down on every layer from 60% to 45%-50% and merge and then i duplicate the layer one more time and set the very middle section on levels to 1.10 and then i flatten
