1. A method for adjusting an image for display with a reduced source light power level, said method comprising:

  • a) creating an input image histogram for an input image;

    b) locating a histogram feature on said input image histogram;

    c) finding an input image histogram feature code value corresponding to said histogram feature;

    d) determining an enhanced feature code value based on said input image histogram feature code value and a reduced source light power level;

    e) establishing a tonescale correction curve fitted to said enhanced feature code value; and

    f) processing at least a portion of said input image with said tonescale correction curve.
