numbers. This will produce an image with greater clarity. If you wish to expand one part of the histogram, rike where there are a large grouping of pixels, move the middle triangle toward that part. Since there are always 128 channels between the middle triangle and the end point triangles, adjusting them closer together gives the pixels in that region more channels to work with, and maximize the detail captured.

Color Balance

This control allows you to improve the look of your image, while retaining the detail as you adjust the color levels in the shadows, midtones and highlights. Shadows effects the dark pixel values of the image, midtone effects the middle range, or dominate range, of pixels, and highlights effects the light pixel values.
