Range
Assume your original data are rescaled.
To achieve high contrast, the computer scales a smaller range of data with the same
number of colors as it used for rescaling.
Any data value greater than the maximum in the displayed data range is represented by
the brightest color (white). Any data value lower than the minimum in the displayed data
range is represented by the darkest color (black).
Now only a fraction of the original data range is represented by the total number of colors.
Decreasing the displayed data range produces high contrast.

To achieve low contrast, the computer scales a larger range of data with the same
number of colors as it used for rescaling. Thus the original data are represented by a
smaller range of colors.
Increasing the displayed data range produces low contrast.
