    Map Coloring

    Usage

    ColorToneMapping[image] applies a tone mapping to color values in image so as to make variations of luminance visible even in small intervals of the dynamic range. ColorToneMapping[image, c] maps colors by compressing the overall range of luminance values by a factor c. ColorToneMapping[image, range] applies a mapping only to colors whose initial luminance lies in the specified range. ColorToneMapping[image, {range, c}] takes the specified range of colors and compresses their overall luminance values by a factor c. ColorToneMapping[image, {{range1, c1}, {range2, c2}, ...}] uses different compression factors ci for different ranges rangei. ColorToneMapping[image, spec, s] uses the color compensation factor s to correct for saturation distortion introduced during tone mapping.

    Basic example

    Apply tone mapping to a high dynamic range image: In[1]:=img=Import[ExampleData/Balls.exr] Out[1]= In[2]:=ColorToneMapping[img] Out[2]=
