There are three tools to use for the most intuitive tonal corrections. The
first is the colored sliders at the top of the screen to the right of each of the
three color wheels. The first, rainbow-colored vertical bar in each group
adjusts hue. The middle bars adjust the chroma or saturation level of the
image. And the black/white bars to the right of each group adjust the level
of the black point, midtone (gamma) distribution or white point in the
shadow, and midtone or highlight tonal ranges, respectively ( Figure 2.10 ) .
