Specifying a white point changes all the colors in the image. The white point is the
color that Photoshop defines as pure white, and it adjusts all other colors accord-
ingly. To set an accurate white point, select a white area in the image.
3. Click a white stripe on the girl's dress.
The color tone of the image changes dramatically. You can click different white
areas, such as the child's sailor dress, a stripe on the woman's dress, or the girl's
sock, to see how each selection changes the color.
In some images, adjusting the white point is enough to remove a color cast and
correct the tone of the image. Here, selecting a white point is a good start. You'll
use a Levels adjustment layer to fine-tune the tone.
4. Click Levels in the Adjustments panel to add a Levels adjustment layer.
The Levels histogram in the Properties panel displays the range of dark and light
values in the image. You'll learn more about working with levels in later lessons.
Right now, you just need to know that the left triangle represents the black point
(the point Photoshop defines as the darkest in the image), the right triangle repres-
ents the white point (the lightest in the image), and the middle triangle represents
the midtones.
5. Drag the left triangle (blacks) under the histogram to the right, where the
blacks are more pronounced. Our value was 15.
6. Drag the middle triangle a little to the right to adjust the midtones. Our
value was .90.
