Do you see that "[1]"? That means there's a footnote. If you look at
the footnote, it says:
1. (1) In practice, there are some non-linearities in the darkest
shadows and brightest highlights. Also, some cameras, e.g the
Nikon D2X, preprocess the sensor data before the ADC.
I admit I deliberately suckered you to see whether you'd actually read
