Manipulating the Histograms
Manipulating the image’s histograms is a quick and powerful method of of set-
ting its tonal range. To do so, click on Histograms in the RGB Control window
(see Figure 3–6).
The window displays the input density histogram and the output reflectance his-
togram. The input histogram can be adjusted to show all three RGB channels
together or each channel individually. To adjust the limits, slide the white slider
(highlight) and/or black slider (shadow) to the desired position.
The Output Reflectance histogram is a static display that cannot be adjusted. It is
designed to show how your adjustments will affect the image when output.
Note:
Minor adjustments to histograms have
strong results. Move the sliders in small incre-
ments to avoid distorting your range values
excessively. (Remember to update the image
regularly to view your changes.)
