Seems strange to say it, and maybe others don't need the reminder like I do, but in this digital age it's helpful to make prints and have an analog experience with your photos. This morning I was home with Jack, in the midst of a fearsome Sorry! Sliders contest, and I noticed the window light moving across a small framed print on the wall. So I grabbed a camera and the lens that happened to be attached to it.
Game interrupted, Jack went with the flow. And we had a talk about about the sun's movement, the low angle of winter sunlight, and shadows.
Then we resumed our game. He won.
