Two of my grandsons. We visited snowy Yosemite Park and they had a great time throwing snowballs. When we returned to our room, they were content to lay side by side watching a movie on our tablet. I saw them, stuck a speedlight gelled 1/4 CTB into the tablet and dragged my shutter to pick up a bit of the ambient from a nearby lamp.
