Genuine Fractals PrintPro...for resizing,without killing the quality. Extensis MaskPro...does a bit better than PS with masking and selections. EyeCandy...only for the "noise filter"..gives more options than PS. Clouds(free on the net)..once again..same as PS,but with more options and control. Flaming Pear's Flood...don't use it that often,but does come in handy. Waiting to see what the new filter(due out the end of this month)from WorldBuilder has to offer...import 3D object files into PS,move, rotate,add shadows,then commit to a layer..hmmmm SWAMP
