The characteristic curves gives you basically information about the way a light sensitive material reacts to exposure. You can read
the sensitivity (speed)
the average contrast (gamma) of the formed image
the exposure range (min. to max. exposure)
the dynamic range (min. to max. density)
the varying way it renders the image over the exposure (bendings of the curve)
the possible variation in exposure with unchanged contrast of the images (latitude)
The form of the END curves tells you something of the quality of colour reproduction.
