If you made a selection in the image, do one or more of the following:
•
In the Destination Image area, select Ignore Selection When Applying Adjustment if you’re applying the
adjustment to the entire target layer. This option ignores the selection in the target layer and applies the adjustment
to the entire target layer.
•
In the Image Statistics area, select Use Selection In Source To Calculate Colors if you made a selection in the source
image and want to use the color in the selection to compute the adjustment. Deselect the this option to ignore the
selection in the source layer and use the colors in the entire source layer to compute the adjustment.
•
In the Image Statistics area, select Use Selection In Target To Calculate Adjustment if you want to use only the
colors in the selected area of the target layer to compute the adjustment. Deselect this option to ignore the selection
and use the colors of the entire target layer to compute the adjustment.
6
To automatically remove a color cast in the target layer, Select the Neutralize option. Make sure the Preview option
is selected so that your image is updated as you make adjustments.
7
To increase or decrease the brightness in the target layer, move the Luminance slider. Alternatively, enter a value
in the Luminance text box. The maximum value is 200, the minimum is 1, and the default is 100.
8
To adjust the range of color pixel values in the target layer, adjust the Color Intensity slider. Alternatively, enter a
value in the Color Intensity text box. The maximum value is 200, the minimum is 1 (which produces a grayscale
image), and the default is 100.
9
To control the amount of adjustment applied to the image, adjust the Fade slider. Moving the slider to the right
reduces the amount of adjustment.
10
Click OK.
To remove a color cast
The Match Color command can adjust the brightness, color saturation, and color balance in an image. The advanced
algorithms in the Match Color command give you better control over luminance and color components of the image.
Because you are adjusting the color in a single image rather than matching the colors between two images, the image
you’re correcting is both the source and the target image.
1
Choose Image > Adjustments > Match Color.
2
In the Image Statistics area, make sure None is chosen in the Source menu. The option specifies that the source
and the target are the same image.
3
To automatically remove a color cast, select the Neutralize option. Make sure the Preview option is selected so that
your image is updated as you make adjustments.
4
To increase or decrease the brightness in the image, adjust the Luminance slider. Moving the Luminance slider to
the left darkens the image, and moving the slider to the right brightens the image. The luminance control tries not
to clip pixels (change them to pure black/no detail or pure white/no detail) in either the shadows or highlights.
However, it may clip pixels because an image can have only either 8-bit or 16-bit values.
5
To expand or reduce the color pixel values in the image, adjust the Color Intensity slider. Moving the Color
Intensity slider to the left reduces the color range, and the image becomes monochromatic. Moving the Color
Intensity to the right increases the color range and intensifies the colors.
6
To control the amount of adjustment applied to the image, adjust the Fade slider. Moving the slider to the right
reduces the amount of adjustment.
