I took that photo a year ago and wanted to publish it using a B&W convertion.
But something was missing. I was losing the magic of the moment I captured.
Recently I was looking at this photo on an uncalibrated monitor where it appeared blue.
And I found the magic was there. So here it is in Blue and White to find back the... Blue mystery!
For information, I used two ND filters to better isolate the waterfall from the rocks
and then applied vignetting effect with Lightroom.
