I set up my Nikon D500 with Tamron 70-200 near the fountain yesterday in 108 degree heat because the birds were flocking in for water. I also set my DB-700 speedlight on camera with my little SB-600 on a stand to the side. I framed the shot I wanted and then gave the remote trigger to my 5-year-old son and told him when a bird lands on the second cup, take a picture then count to 5 to make sure the flash recycled before taking another. The below are the best of what he captured.
