Essentialy, the author, Kendal Preston, Jr. argues that we don't need more than 8 bits of color info, and by doing histogram analysis of a medical photomicro- graph of stained cells shows that most of the histogram bins are empty, and that dynamic data compression is possible by using a color map with various criteria to assign a color to a color values with a high frequency. I don't agree that we should not consider >8 bit in color workstation design, and we should consider that his scanner may not have the dynamic range resolution to more evenly fill the color distribution of his scanned images.
