Just released an album shot in super low light at ISO 51200 with the Nikon D4 and Dorothy of SnobAffair for those of you eager to know what can be captured at such a crazy high ISO and an f/1.4 lens. Colors were really unexpected as I was really aiming at complete blackness so I managed to process a few decent files for you guys to see. :)
