Adobe Photoshop Help Using Help | Contents | Index Applying Filters for Special Effects Back 323 To load images and textures: 1 Choose the filter you want from the appropriate submenu. 2 In the filter's dialog box, choose Load Texture from the Texture pop-up menu, and locate and open a texture image. All textures must be in the Photoshop format. Most filters use only the grayscale information of a color file. Defining undistorted areas The Displace, Shear, and Wave filters in the Distort submenu and the Offset filter in the Other submenu let you treat areas undefined by the filter in the following ways: • Wrap Around fills the undefined space with content from the opposite edge of the image. • Repeat Edge Pixels extends the colors of pixels along the image's edge in the direction specified. Banding may result if the edge pixels are different colors. • Set to Background (Offset filter only) fills the selected area with the current background color. Using texture and glass surface controls The Conté Crayon, Glass, Rough Pastels, Texturizer, and Underpainting filters have texturizing options. These options make images appear as if they were painted onto textures such as canvas and brick or viewed through glass blocks. To use texture and glass surface controls: 1 From the Filter menu, choose Artistic > Rough Pastels, Artistic > Underpainting, Distort > Glass, Sketch > Conté Crayon, or Texture > Texturizer. 2 For Texture, choose a texture type or choose Load Texture to specify a Photoshop file. 3 Drag the Scaling slider to enlarge or reduce the effect on the image surface. 4 Drag the Relief slider (if available) to adjust the depth of the texture's surface. 5 Select Invert to reverse the surface's light and dark colors. 6 For Light Direction, indicate the direction of the light source on the image. Tips for creating special effects Try the following techniques to create special effects with filters. Create edge effects You can use various techniques to treat the edges of an effect applied to only part of an image. To leave a distinct edge, simply apply the filter. For a soft edge, feather the edge, and then apply the filter. For a transparent effect, apply the filter, and then use the Fade command to adjust the selection's blending mode and opacity. (See "Blending filter effects (Photoshop)" on page 322.) Apply filters to layers You can apply filters to individual layers or to several layers in succession to build up an effect. For a filter to affect a layer, the layer must be visible and must contain pixels-for example, a neutral fill color. (See "Filling new layers with a neutral color" on page 296.)
