Thanks for your comments John and Warren. I spent most of my precious little down time last week playing with / swearing at / cursing PI and I think I'm finally coming to grips with its basics. Once I got beyond the naughty words and tanties, I actually started to like PI ... but it's still a beast and yep John, mask functions are *nothing* like PS and somewhat limited in comparison. I used only two simple masks for local histogram tweaking of the flame and horse's backdrop; most of the effort went into producing a HOO palette and then learning about the saturation tool which ultimately produced the second image below. Time to get back to playing with / swearing at / cursing PI
