I didn't add any effects. Z Fold is sentient. Best dog that I've ever had. Newfs, etc. Poodles are amazing.
Wasn't suggesting you did, just pointing it out. Seen a few photos on here that had that same look just by accident through a lucky trick of the light. It's the sort of pic you could print out, stick it in a frame and caption it "Photo or painting?", so while hanging on a wall people can puzzle over that question.
