Maybe the issue is the definition of contrast. The dynamic range does not
change since Dmax and Dmin stay the same. But the "stretching or bunching
either end of the tonal range" causes the stretched range to have higher
contrast and the bunched range to have lower contrast. Contrast is the slope
of the curve.
