Lumolab noise test chart for Pentax K-7 at 2900°K and ISO 100.

This photo was underexposed by 9 stops! In order to make the resulting (totally black) photo visible within an 8-Bit file format as allowed by SmugMug, I pushed exposure +9EV before saving as JPG. The result is seen above and theoretically, corresponds to ISO 51,200.
