ptg Extending Photoshop Introduction Adobe Photoshop comes in two editions: Photoshop CS5 and Photoshop CS5 Extended. Photoshop CS5 is a subset of the Extended edition. Photoshop CS5 Extended edition has all the same features included in the standard edition. However, the Extended edition also contains additional features that are geared towards creating more sophisticated content. If you need to count objects in an image for statistical purposes, you can use the Count tool. The Count tool allows you to manually click an image and track the number of times you do it. If you need to physically count the number of elements that appear in a photo, you can click the image to add numbers, so you don't have to remember them. If you need to measure an area in an image and track the measure- ment data for statistical purposes, you can use the Measurement feature. The Measurement feature allows you to compute and track data points, such as width, height, area, and perimeter. Photoshop Extended allows you to create a timeline- based animation. If you want to add video to a document, you can create a new video layer. You can create a video layer from a file, or create a blank one and add a video file to it later. After you insert a video layer, you can modify it using the Animation panel in Timeline view. You can change the start and stop points, trim frames, add a fade-in or fade-out, or add animation using keyframes. In addition, Photoshop Extended provides vast improve- ments to the way you work with 3D files. You can create a 3D model by using the 3D panel or commands on the 3D menu. You can create a 3D model from a text layer, a selection, or a layer mask in a document to convert it to a 3D model or open an existing 3D file. Artists can paint directly on 3D objects without having to render them in another program. 20 20 What You’ll Do Count Objects in an Image Take Measurements in an Image Align and Combine Layers Open Video Files and Image Sequences Create a Video Layer Modify a Video Layer Split a Video Layer Clone Video Layer Content Set 3D Preferences Create 3D Models Create 3D Models Using Repousse and Preset Shapes Change Render Settings Modify 3D Models Browse 3D Content 477 From the Library of Wow! eBook ptg 478 Chapter 20 If you need to count objects in an image for statistical purposes, you can use the Count tool in Photoshop Extended.

For Your Information 5 From the Library of Wow! eBook ptg 482 Chapter 20 Ever wanted to replace or delete parts of an image that have the same background or combine images that share overlapping content? In Photoshop, you can do it with the Auto-Align Layers and Auto-Blend Layers commands. The Auto-Align Layers command automatically aligns different layers that contain similar content. One layer is assigned to be the reference layer and all other layers are aligned to the reference layer in order to match everything up. You can manually set the reference layer, or let Photoshop automatically choose it for you. Sometimes when you align images, a visible stitching appears between them. You can use the Auto-Blend Layers command with RGB or grayscale images to create a smooth appearance between the aligned images. Auto-Blend Layers uses layer masks to remove content differences between the images. Aligning and Combining Layers Align Layers Open a document. Duplicate or place the images you want to align on different layers. To set a ref erence layer, se lect the layer you want, and then click the Lock button on the Layers panel. ◆ If you don’t have a locked layer, Photoshop will create one for you. Select the layers you want to align in the Layers panel. Click the Edit menu, and then click Auto-Align Layers. Click one of the layout alignment options: ◆ Auto. Analyzes the images and uses either the Perspective, Spherical, or Cylindrical layout. ◆ Perspective. Creates a stretched or skewed effect on the side images. ◆ Collage.
