My husband took only the following 7 photos, one at a time (not in the order below) but they happened to work out into a progression series. It only took him 6 shots to work out the timing with the digital delay and to get photo #4 below. Well done!
After the photo shoot, I realized I hadn't extended the rod on the toy holder and he was jumping much better after I did that, but by that time my husband was wandering around the boat launch area a bit with his Beagle who also went for a swim.
