Thanks, Paulo. I just started Zen Camera by David Ulrich and he recommends an exercise of making photographs just to make them, without thinking or evaluating, and to see what draws the eye. I figured I have more than 50K in my LR catalog and that I'd go back through them to see what draws my eye. This one goes back to 2014 and I had skipped over it back then, so it was untouched in post. I'd shot a bracketed series, just for grins or I was thinking about HDR, so I took the brightest exposure (ETTR) into LR to have a look and see where my PP wandering would take me. Maybe a pattern will resolve. I hope.
