AUGUST 01, 2002 Photoshop Compositing: Water Effects
The displacement map Now we're going to create our ripple effect, which we'll also be using as a displacement map. A displacement map is used to distort another image along the areas of lightness and darkness in the displacement map image. Well, you'll see how it works in a little bit. [an error occurred while processing this directive] To begin, create a new file the same dimensions as your original image. Once you've done this, follow these steps. 1. Make sure your foreground color is black and your background color is white. Then choose Filter > Render > Clouds. This will create a black and white cloud layer on your new image. 
2. Choose Filter > Render > Lighting Effects, and apply the default lighting effect. You can play around with it as you see fit. Actually, this step isn't necessary, but I like the way this effect plays with contrast and brightness. 
3. Choose Filter > Distort > Ocean Ripple. I used a ripple size of 8 with a displacement of 16, but you can play around with the values for variety. 
4. Apply Filter > Blur > Motion Blur with the same settings as before--an angle of 0 and a distance of 25. 
5. Now select Edit > Transform > Scale. When the transformation handles appear, pull the top, middle handle down until it's approximately the same size as the mirror-image portion of your original image. Make it a little bigger just to be safe. When you're done with the transformation, hit the Return or Enter key to commit to the change.. 
6. Choose Edit > Transform > Perspective. When the transformation handles appear, drag the bottom right corner handle as far right as you can. 
7. Now go in and adjust the brightness and contrast of the image using Image > Adjustments > Brightness/Contrast. I took my brightness to -30 and my contrast to +15. 
8. Now, for our purposes on this particular piece, we're going to want to lighten up the top portion of this image considerably and also the two bottom corners. To do this, choose the Dodge tool from the tool palette. Drag it along until you get something like the image below. 
9. Command-click (Macintosh) or Control-click (Windows) on the layer in the Layers palette. Then choose Image > Crop. 10. Save the image, but don't close it. You'll need a saved file to use for the displacement effect. So that's it for the displacement map. Now all we have to do is put the two files together and then finish up with a little clean-up operation or two.
