First Light. Leitz Summicron 50mm DR

On the mornings when I arise early - at 06:30 - to go to work, I have noticed this scene playing out on the bedroom dressing table.  It's a holiday today, but we had an international call at just the right moment, as an early sunbeam insinuated its way around the shade.  I went to fetch the camera to record it.  
Despite appearances, the room was very dark, and I had to bump up the ISO to 12,800, which I've never done with the GX9.  There's remarkably little noise.
