Checking tonal range and changing gray balance with the color wheels
The two color wheels in the Highlight/Shadow window show the lightest 3% and darkest 3% of
pixels in the image, respectively, displayed in green.
• Within these areas, the greatest concentration of pixels is shown in red.
• A blue cross indicates the tonal value of the active reference point in the feedback windo
w.
Thus, you can easily check whether any given point falls within the lightest or darkest part of
the image.
• By dragging the green/red area in one or both color wheels to a new position, you can neutral-
ize, reduce or increase color cast
.
• To neutralize cast, drag the red area to the center of the color wheel.
• To make any given part of the image neutral, double-click on it in the feedback windo
w and
drag the blue cross to the center of the color wheel in the Highlight/Shadow window.
• The results of your changes are shown interactively in the feedback window and Densitometer
window.
