Exercise 4.1. One staple of the texture-building tutorials was the Mosaic filter. Look through the Image: Filters menu for other filters that you could use to build different textures in a similar way.

Exercise 4.2. Many steps were involved in creating the texture shown in Figure 4-42. Try repeating or omitting some of the steps and see how many different results you can achieve.

Exercise 4.3. In the example shown in Figure 4-48, we used a Radial blur. Try choosing a Linear blur or a Zoom blur and see how the result changes. Adjust other parameters or other steps of the process to improve the result.

Exercise 4.4. The example of the Scott effect was very simple. Use the basic principle to transform a photograph of a metal object. When you’re finished, the object should appear to be rusted in places but still recognizable.

Exercise 4.5. We used the Lighting Effect filter in two different ways (see Figure 4-60 and Figure 4-84 on the preceding page). Using what you understand about the function of this filter, try to re-create the texture of raw uncut gold.

Exercise 4.6. As seen in Figure 4-73, the Emboss filter produces a grayscale result. Build a similar embossed logo in copper or gold.

Exercise 4.7. Automatically generate a logo using Image: File > Create > Logos > Cool Metal. Without looking at the way it’s built, try to recreate the elements of the logo: relief letters, a color gradient, cast shadow, reflection. Hint: Try one effect at a time and then combine them.

Exercise 4.8. The textured logo shown in Figure 4-86 is rather minimal for a final product. Use a different texture for the lettering. Then add a textured background on which the logo casts a shadow bumped by the texture’s relief.
