In-Depth Information
To see the darkest area of this image, press and hold the Alt/Option key and slide the shadow slider to the
left.
Depending upon the input device you have, many areas display as the darkest areas of an image.
This is an indication that the input device, whether a scanner or camera, does not have a large dy-
namic range of tonal values that it can record. You might have to take a logical guess as to what is
the darkest part of the image.

Make sure that the Set black point eyedropper is selected, and then press and hold the Alt+Shift (Win-
dows) or Option+Shift (Mac OS) keys and click the darkest shadow area to leave a color sampler.
Press and hold the Alt/Option key along with the Shift key and click the darkest area.

With the Sample in image to set black point eyedropper still selected, click the color sampler that you
dropped on the image. This has now been set as the darkest area of the image, using the values you in-
put earlier in this example.
You should already see a difference in the image—a slight color cast has been removed and the colors
look a little cleaner—but you are not done yet. The next step involves balancing the midtones (middle
values) of the image.

Leave the Curves Properties panel visible for the next exercise.
