        # Brightness is (similar to) y = x**alpha and part of gamma transformation from linear sRGB to RGB.
        # Exposure and brightness both dilate the histogram towards highlights.
        # Exposure dilatation is uniform (homothety), brightness dilataion is
        # maximum for the midtones and the highlghts are preserved.
        # As a consequence, normal workflow begins with the adjustment of exposure,
        # to fill the entire range of the histogram and to adjust the highlights. Next,
        # one adjusts the brightness to put the midtones at the level we want them to be.

        ######################
        # From libraw and dcraw sources:
        # Exposure and brightness are curve transformations.
        # Exposure curve is y = alpha*x, with cubic root ending; it is applied before demosaicing.
        # Brightness is (similar to) y = x**alpha and part of gamma transformation from linear sRGB to RGB.
        # Exposure and brightness both dilate the histogram towards highlights.
        # Exposure dilatation is uniform (homothety), brightness dilataion is
        # maximum for the midtones and the highlghts are preserved.
        # As a consequence, normal workflow begins with the adjustment of exposure,
        # to fill the entire range of the histogram and to adjust the highlights. Next,
        # one adjusts the brightness to put the midtones at the level we want them to be.
