A Peek into a Later Chapter
I’m going to take this opportunity to discuss Apply Image, something I’ll cover in depth in
Chapter 4, “Texture, Color, and Layer Effects.” Apply Image has to be one of my all-time
favorite adjustments in Photoshop. I’ll reserve most of my praise until later, but because it
works for this effect I’ll dip into it just a bit here.
Apply Image allows you to blend two images together. Sounds simple enough, until
you discover the number of ways you can blend those images. The effects can be rather
astounding. For this example, however, all you need to know is that both images must
have the exact same dimensions in pixels. I’ll discuss why in Chapter 4, but for now simply
adjust the size of the
Map.jpg image to match the size in pixels of Back.jpg (see Figure 1.55).
Figure 1.55 For Apply Image to work,
both documents (or all that will be used in
creating your final image) need to have the
exact same dimensions in pixels.
You may now use the displacement map to warp the Map.jpg image. Select the map
photo and choose Filter
→ Distort → Displace. The Displace dialog box will then ask you to
what Horizontal and Vertical scale you would like the warp to take place. A setting of 10
for each should work fine in this instance, because the images are both 300 ppi. If they were
of lower resolution, then lower Scale settings would be in order.
The Displace filter uses a second image (displacement map) to determine how a layer or
selection will be distorted.
Also in the Displace dialog box you are asked to choose either Stretch To Fit or Tile.
Stretch To Fit works best here, because there is no need to have the edges repeat. For the
same reason, Wrap Around should be selected under Undefined Areas (see Figure 1.56).
After these settings are selected, click OK to apply the filter.
