■ Displacement Mapping 25
But wait; there’s more! Now Photoshop will ask you what .psd image it should use as
a map. By default it will take you to the location on your hard disk where you saved the dis-
placement map: simply select it and click OK. The
Map.jpg image will warp to conform to
the contours of the
Back.jpg photo.
Now on to Apply Image. After you choose
Image
→ Apply Image, you use the Source drop-
down list at the top of the dialog box to select the
image you would like to apply to your photo. For
instance, say you would like a darker, more color-
rich version of your current image. You could use
Apply Image with the same photo set as the
Source, and the Blending mode set to Darken to
accomplish this (see Figure 1.57). I’ve applied the
map to the photo of the back (see Figure 1.58).
The combination of displacement maps and
Apply Image are only the tip of the iceberg. I’d
love to continue this topic now, but I’ll force myself to wait until Chapter 4. In the mean-
time, I have one more cool item to demonstrate in this chapter.
Figure 1.58 Applying an
image to itself can have the
effect of richer, more vibrant
colors.
Figure 1.57 Apply Image can use the
document you are working on as the
Source image.
