I tried to snap a few cat photos this evening. The cat-sisters get the being-photographed thing. They let you activate the focus, then in the half-heartbeat while the iPhone is preparing to take the photo, they move. They are masters at this timing.
However, very late in our visit, I managed to outwit their “system” and get one in focus. Not much of a photo, but I reveled in my little basically-in-focus-victory!
