For example, you can choose to view or hide a mask, or even change its color. If the image you're working on is in a transparent layer you can even choose to view the image with or without the other image layers. How you view the image is up to you; however, having choices gives you greater control over the final results. 5 4 From the Library of Wow! eBook ptg 342 Chapter 14 You may have noticed the Load Mesh and Save Mesh buttons, located at the top of the Liquify dialog box. A mesh is a predefined Liquify oper- ation. When you activate the mesh option, a mesh or grid is placed over the image, and then as you use the Liquify tools, the mesh distorts and bends. After applying a lot of work to a particular image, it's quite pos- sible you might want to use that exact mesh on another image. That's where the Load Mesh and Save Mesh options come into play. With the click of a button you can create a mesh and use it over and over again. Creating a Liquify Mesh Create a Liquify Mesh Open a document. Select the Layers panel, and then select the layer on which you want to use the Liquify tool. Click the Filter menu, and then click Liquify. Select the Show Mesh check box.

You can display the distortion created by the Liquify tools. Check this option to display a mesh (grid) over the image preview. When you select the Show Mesh check box, a mesh is applied to an image, which distorts as you apply the Liquify tools. When you clear the Show Image check box (dimming the image), you get a visual grid that repre- sents the distortion values applied to the image. From the Library of Wow! eBook ptg Chapter 14 Manipulating Images with Filters 343 Applying a mesh to an image is a lot easier than redoing a particular Liquify operation and to be honest, it would be virtually impossible to reproduce a Liquify adjustment from scratch. That's why Adobe gives you the option of creating, saving, and loading your very own personal- ized meshes. Applying a Liquify Mesh Apply a Liquify Mesh Open a document. Select the Layers panel, and then select the layer on which you want to use the Liquify tool. Click the Filter menu, and then click Liquify. Select the Show Mesh check box. Click Load Mesh. Select a mesh. Click Open. The distortions generated by the mesh are applied to the image. Click OK. 8 7 6 5 4 3 2 1 6 7 8 5 4 Did You Know? You can modify a loaded mesh. Open a mesh, and then use the Liquify options to further distort the mesh pattern. That way you can create a generic mesh pattern and modify the pattern to fit any design need. From the Library of Wow! eBook ptg 344 Chapter 14 The Lens Blur filter creates a varying depth of field so that certain objects stay in focus and other areas become blurred. What stays in focus and what is blurred is determined by a user-defined selection or alpha channel. When the filter is activated, a depth map is created to determine the three-dimensional position of the pixels in an image. If you use an alpha channel, the black areas in the alpha channel are at the front of the photo, and the white areas are in the distance. Experiment with selections and alpha channel masks to see how pre- cisely you can control the visual effect of blurring in an image. Using the Lens Blur Filter Use the Lens Blur Filter Open a document. Select the Layers panel, and then select the layer to which you want to apply the Lens Blur. Create a selection or alpha mask to control the blur. Click the Filter menu, point to Blur, and then click Lens Blur. The Lens Blur dialog box opens. 4 3 2 1 3 2 1 See Also See “Using the Gaussian Blur and Despeckle Filters” on page 160 for information on using filters.

Photographers place colored filters in front of a camera lens to adjust the color balance of the image and control the color temperature of the light transmitted through the lens. In addition to simulating a color filter, the Photo Filter command also lets you select a color preset and apply a specific hue adjustment to an image. If you want to apply a custom color adjustment, the Photo Filter command lets you specify a user- defined color using the Adobe Color Picker. Working with Photo Filters Work with Photo Filters Open a document. Select the Layers panel, and then select the layer to which you want to apply the Photo Filter.
