damn Sami, this is awesome... almost inverted (my fave)

oh and I like that you used a shot we are all familiar with cause it was just yesterday when we saw it. (well yesterday for me)

Partial invert aka 'Sabattier effect' aka solarisation ;-) en.wikipedia.org/wiki/Solarisation

Yes, I wanted to give another example for TSC folks on how to use sliders =) So, there are sliders to use practically everywhere. But recently I have found to use this curves tool creatively. Well, I have known how to use it for very long time, but only during last months started to really use it in practice.

psychedelic bathroom, not very relaxing :D

Seems the same result/principle like PS' "Luminisation"

Possibly... I searched information on the use of "luminosity masks", and for me it looks just way too complicated! =D

I simply used curves tool in the similar way as it is used for "solarisation" (Sabatier effect):
