INDEX

The following figure displays the histogram when the flower is cropped. Notice the pixels are spread more evenly, although still leaning to the darker side of the midtones.

You can adjust the histogram so the pixels are spread move evenly throughout the range of tones in the image. The procedures for adjusting the histogram are in “Change Tone Using the Histogram Tool” in Chapter 3, “Scanning.”

The easiest way to affect the redistribution of pixels is to adjust the triangles at the bottom of the histogram. When you move the Mid-point slider to the left, a larger number of pixels fall into the midpoint range, and more midtone shades become visible.

Move the triangles to adjust the pixel distribution in the preview image.
