The RAW file downloaded fine for me,, This is my attempt at it, Selected the water so that I didn't change it, adjusted the saturation on the upper part of the photo, mainly the yellows and greens. A bit of RGB curves adjustments (I am terrible with curves) Resized and sharpened with USM. I didn't know if the rocks were supposed to be red, or if they were gray like lava is that I have seen, so left them reddish. It will be interesting to see the other finished photos. DAve
