“Wake up and smell the coffee.” I think that here it refers to suddenly realizing that what you were looking at is not the point of the picture. I got a great shot of the urchin, colorful, composed, and there’s a resting fish in the background. That wiry barbed plant life in the foreground and all around are really brittle stars. Never saw one before so I didn’t have a clue… J got the shot and later someone told her about them. (I was still seasick on board.) Me? I never did get a single decent shot. It’s lucky for me that she noticed they were moving unnaturally against the current. Now that I know what I’m looking at, it’s a bit spooky. Credit J on this splendid shot.
