underneath the eyedropper. Click in the black area created by the threshold
layer to place a color sampler target black point.
Step 6: Throw away the threshold adjustment layer

Layers palette, or just turn the visibility of in the Layers palette.
Step 7: Create a Levels adjustment layer
Go to the adjustment layer icon at the bottom of the Layers palette and
choose Levels or Curves.
Step 8: Set the White Point
Single-click on the white eye dropper to select the dropper, and click on your
image in the center of the color sampler target you created for the white
point.
Step 9: Set the Black Point
With the Levels dialog box still open, single-click on the black eye dropper to
select the dropper, and click on your image in the center of the color sampler
target you created for the black point.
Hint:
Finding a neutral point
in an image for color
corrective purposes is
often a matter of “click
i shing”. Try clicking on
gray hair on humans or
animals; shadow areas,
rocks and clouds are
often places that contain
a good neutral.
Step 10: Set Neutral Point if there is one
Click on the gray dropper, and click on an area within the image that should
be a neutral gray. It is ok to go “i shing”, i.e. just clicking around the image
with the gray eyedropper to get dif erent results if you do not know where a
neutral exists.
