I gotta say, I don't know what a luminosity mask is, I'll read up on that after work today. Thanks iffy!

 not for long!

 Hmmmm so HDR but better? I was playing around with HDR shots yesterday as well taking bracketed shots, but not taking too much thought into foreground exposure in some, and background exposure in others... really trying to up my landscape game so gonna keep reading on this.

 kinda..its a way of making masks ( like a selection) using the brightness value of the pixels, eg I want to just change the curve for the dark reds, or alter just the clouds or sky etc, makes it very fast. its free if yo sub and works best with PS CC versions not sure if it works on lightroom?

 I have the CC Subscription so I can put PS on my PC. I've been reading up on it and HDR and stuff. Got a lot to learn and try... will definitely get Luminenzia downloaded!

 @StUone7: I took the liberty of playing with it a bit
