I love this moment; I love this photo.
For me, this photo captures pure excitement and joy; the kids are jumping up and down with their dad, past bedtime, celebrating the first day of winter break.
I watched the excitement building, grabbed my camera, quickly turned up the ISO, and captured the moment. Thankfully, my priority had been in the moment, not on the correct camera settings; had I stopped to set my camera properly, I would have missed this moment, completely.
This is perfect in its imperfection.
