8. Deactivate the selection (Image Menu ➤ Selections ➤ None). Add a layer mask

to the Color Correction layer (Right-click Layer ➤ Add Layer Mask) .

9. Using black as the active color and a large, soft brush, paint the yellow tinge out.

Vary the brush opacity, if necessary, as you work (Figure 4-49 ).

10. Now that the image is evened out, duplicate the background layer, then merge

the Color Correction layer down onto the background layer copy. (It will now
have the same name as the background layer.)

11. Duplicate the layer and rename it Levels Correction. Open the Levels dialog

(Image Menu ➤ Colors ➤ Levels). We're going to adjust each color channel
to further correct the color and tone in the image. First, select the Red color
channel, and move the black point slider to the right, until the value is about 56.
Move the white point slider slightly to the left, until the value is about 233. The
midpoint slider should be set at about 1.15 (Figure 4-50 ).
