Setting the Densitometer Measuring Point
You can fix the densitometer measurement point to a specific location on
an image to get its color values and accurately adjust the tone curve
based on those values.
1 Move the mouse pointer to the point on the image you want to mark for
measurement.
2 Hold down the Shift key and click the image. A red cross appears
at that point on the image and remains there until you press the Shift
key while clicking the image again.
3 Now open the Gradation Curves dialog box (see Adjusting Tone
Curves for details). The red, green, and blue curve anchors indicate
the settings for those colors at the densitometer measuring point. Enter
new values for the colors you want to adjust based on the current
densitometer values.
Before setting the
densitometer
measuring point,
make sure you’re
in pixel view (the
button appears
in the rotation
tools bar). If you not in
pixel view, click the
button.
