Select an image.

If necessary, click the Tint disclosure triangle in the Enhance area of the Adjustments
inspector or the Adjustments pane of the Inspector HUD to reveal the Tint color wheels,
then select the White Tint eyedropper.
The pointer changes to the Loupe, showing a magnified view of the target area. By default,
the Loupe is set to magnify the image to 100 percent (full size). If necessary, you can
increase the magnification of the Loupe by pressing Command–Shift–Plus Sign (+). For
more information about the Loupe, see “

Position the target area of the Loupe over the lightest (white) pixels in the image,
then click.
The tint (hue and saturation) of the white values in the image is set to remove the color
cast in the highlights.
Important:
Make sure that there are no dark pixels in the target area of the Loupe. Dark
pixels in the target area can skew the white tint calculation, making the image appear
different than intended. A simple way to avoid errant dark pixels is to increase the
magnification of the Loupe by pressing Command–Shift–Plus Sign (+).
Click the disclosure
triangle to reveal the Tint
color wheels.
Select the White Tint
eyedropper to activate
the Loupe.
