No, the artist wasn’t on acid. (Good click-bait title though, don’t ya think?) If anything, that would be the photo editor (that would be me) who would be on acid when I tweaked the landscape with Photoshop to make it all “swirly” while the artist’s easel stayed stone-cold sober.
The effect is not so noticeable when the image is reduced, but you can view (and download) the full-sized image (2560 x 1440) from the lightbox that comes up when you click/tap the image above.

… and, to reiterate, nobody was on acid at the time. 🙂
