Tried photographing grandchildren over the Thanksgiving holidays. Their ages are 5, 4, and 2. We all went out to the backyard. I took a Nikon D610 with a 24-120 lens. I got the challenge of my life. They will not hold still for very long. Most of the pics did not turn out. They cannot hold still. They were also wearing big coats and hats, so if they were running their faces were not visible. It was a time of learning.
