According to DxO tests camera have 10 to 12 stops of dynamic range  . Is that correct? Noise can completely screw some lowers values (easily resulting in loss of some stops).

Also here it is said that original dyn range can be 9 to 11 stops, but prints have "only" 6.5 stops.

Human eye has a dynamic range of 6.5 stops.

  If it is like that, why is the human eye much better than cameras to record scenes with high dynamic range?

According to DxO tests, cameras have 10 to 12 stops of dynamic range. Is that correct? Noise can completely screw some lowers values (easily resulting in loss of some stops).

Also Norman Koren says that a digital camera's original dynamic range can be 9 to 11 stops, but prints have "only" 6.5 stops.

In a section on dynamic range, Wikipedia says the human eye has a contrast ratio of around 6.5 stops. If that is the case, why is the human eye clearly much better than cameras to record scenes with high dynamic range?
