Canon EOS 5D ISO 6400?

Somewhere I saw people pushing Canon EOS 5D ISO 6400, 12800. How is this possible?

Together 5D ISO maximum (3200), and the score in a negative EV to push the ISO. Set to -1 EV ISO 3200 gives 6400 and the creation of -2 EV ISO 12800. Image will be underexposed, but the 5D DR enough to hold a large amount of detail in the shadows. The last step is to use your image editor Bookmark achieve information on the back.
