A method for adjusting color tones of an input digital image file to create an adjusted digital image file. A plurality of predetermined curves are provided, each curve specifying an adjusted color tone percentage output as a function of input color tone percentage and representing a combination of midpoint magnitude and contrast different than for any other curve. The method comprises selecting a curve by determining which one of the plurality of curves most closely matches at least two data points. The selected curve is then applied to the input digital image file to produce the adjusted digital image file. |
