Advanced Scanning For example, if you're scanning a photograph of a child standing in shadow, decreasing the gamma value would increase the contrast between the child's skin tone and the shaded area, thus making it easier to see the subject. Histogram Tool A histogram is a graph that represents values as horizontal or vertical lines. The histogram tool uses vertical lines to show the intensity of the various tones in an image. The height of a line indicates the intensity of the tone. Page 40
