Taken during a nighttime walkabout with my Lumix DMC-GX7. It was almost 9 pm, and quite dark out, when I took the picture. ISO was 25600, shutter speed was 1/20 sec, and f-stop was at 4.6. White balance was a bit off, but easily adjusted with Photoshop Lightroom 5.
I think the small size of the grain is quite fantastic given the high ISO.
