Mushroom on the chessboard
Not quite the same kind of move as the Squid on the Chessboard, but still one not entirely expected.

[CA Roadtrip] Shooting ball
Oberwolfach has a Carom table, with the legend connecting it to mathematicians being interested in ergodic theory.
Hearst Castle doesn't care about the mathematics, and thus has both a Carom table and a Billiards table.

[CA Roadtrip] Enough with Big Sur already!
Instead, have the gorgeous sunset light we caught the Golden Gate Bridge in!

[CA Roadtrip] The problem with HDR…
…is sometimes I just can get it to look just right. Here's what'd be a gorgeous use case for the technique: a sunset. Shot into the sun that just barely hides behind a cloud. In front of us, red plants on the ground. A -2.0/0.0/+2.0 exposure bracket certainly gets us everything we need in terms of pixels.
But a straight up and down HDR can't quite distinguish between the darkness of the plants, and the darkness of the darker bits of sky, so we can't quite get the balance right. Gradiented filters just look awkward. So it is in with the mask we go!
A first attempt, I mask with exposure modification while still in Photoshop with 32 bit, before I even flatten the image down from the full on HDR master:
but it doesn't really look good. Possibly because of me being still too clumsy with the masking brush, possibly some other reason, but it doesn't come out quite the way I had hoped.
Second attempt, just layer the +2 and the -2 exposures, and mask in the flowers from the lighter onto the sky and ocean of the darker one.
If anything, I'd feel this looks worse. But then, I'm not sure. Maybe this could've been saved with better brushing in Photoshop. Maybe you all really like this and I'm just being my usual obnoxiously perfectionist self.
I honestly don't know.
