Introduction
Adobe Photoshop comes in two editions: Photoshop CS3 and Photoshop CS3 Extended. Photoshop CS3 is a subset of the Extended edition. Photoshop CS3 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 it. If you need to measure an area in an image and track the measurement data for statistical purposes, you can use the Measurement feature. You can measure any area defined with one of Photoshop’s selection tools, Ruler tool, or Count tool. The measurement feature allows you to compute and track data points, such as height, width, area, and perimeter.
Photoshop CS3 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 palette in Timeline view. You can change the start and stop points (also known as In and Out points), trim frames, add a fade in or out, or add animation using keyframes.
Counting Objects in an Image
If you need to count objects in an image for statistical purposes, you can use the Count tool (New!) in Photoshop CS3 Extended. 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 element appear in a photo, you can click the image to add numbers, so you don’t have to remember it. After you manually count, you can record the count in the Measurement Log (New!). The count numbers are not saved with the document. If you have multiple selections in an image, Photoshop can automatically count them and record the results in the Measurement Log palette.

Taking Measurements in an Image
If you need to measure an area in an image and track the measurement data for statistical purposes, you can use the Measurement feature (New!) in Photoshop CS3 Extended. You can measure any area defined with one of Photoshop’s selection tools, Ruler tool, or Count tool. The measurement feature allows you to compute and track data points, such as height, width, area, and perimeter. Photoshop tracks the measurement data in the Measurement Log palette, which you can customize to display the information you want. Before you start measuring, it’s important to set the measurement scale to specify what you want a specific number of pixels to represent in units, such as inches, millimeters, microns, or pixels. To make it easier to measure, you can place scale markers on an image to display the measurement scale.
Set Measurement Scale

To export data, click the Window menu, click Measurement Log to open the palette, select one or more rows of data in the log, click the Export button at the bottom of the palette, type a filename, specify a location, and then click Save.
Aligning and Combining Layers
PS 3.6
Ever wanted to replace or delete parts of an image that have the same background or combine images together that share overlapping content? In Photoshop CS3, you can do it with the Auto-Align Layers (New!) and Auto-Blend Layers (New!) 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 stitch 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 take out content differences between the images.
Align Layers
Open a document.
Duplicate or place the images you want to align on different layers.
- To duplicate a layer, select the layer, click the Layers Option button, click Duplicate Layers, enter a name, and then click OK.
To set a reference layer, select the layer you want, and then click the Lock button on the Layers palette.
- If you don’t have a locked layer, Photoshop will create one for you.
Select the layers you want to align in the Layers palette.
Click the Edit menu, and then click Auto-Align Layers.

Select the video layer you want, move the playback head to the frame you want, click the Layer menu, point to Rasterize, and then click Video or Layer.
Modifying a Video Layer
PS 7.3, 13.5
After you insert a video layer, you can modify it (New!) in Photoshop CS3 Extended using the Animation palette in Timeline view. You can use zoom in and out to display the Timeline the way you want, and then drag the playhead, also known as the current-time indicator, to the time or frame number in the video where you want to modify it. You can change the start and stop points (also known as In and Out points), trim frames, add a fade in or out, or add animation using keyframes. A keyframe defines a property change to the video layer. When you set at least two keyframes that change properties, such as position, opacity, and style, you create animation.
Modify a Video Layer Duration
Open a document with a video.
Click the Window menu, and then click Animation to display the Animation palette.
Click the Convert to Timeline Animation button to switch to Timeline view.
Use any of the following methods to change :
- Start and End Work Area. Point to the ends of the work area bar, and then drag to change the position.

Cloning Video Layer Content
PS 5.4, 7.3
If you have video or animation frames that you want to retouch or duplicate, you can use the Clone Stamp and Healing Brush tool (New!) in Photoshop CS3 Extended. The Clone Stamp tool allows you to sample content from one area of a frame (known as the source) and paint it over another area of the same or different frame (known as the target). The Healing Brush tool allows you to blend the sampled content from the source with the target to fix a problem. You can use the Clone Source palette to set several samples from one part of a video frame and clone or blend it in another video frame.
Clone Parts of a Video Layer
Open a document with a video layer, and then select it in the Layers palette.
Click the Window menu, and then click Animation to display the Animation palette.
Click the Convert to Timeline Animation button to switch to Timeline view.
Drag the playhead to the time or frame number with the source of the sample you want.

The Clone Source palette contains five clone button for which you can assign samples. Simply, open the Clone Source palette, click a Clone Stamp button, and then select the sample you want. The Clone Source palette save the samples until you close the document. To help you clone the source in a specific location, you can overlap your sample source and show the overlay on the screen. The overlay allows you to view your changes and helps you visualize where to paint. You can show or hide the overlay and change its appearance. In addition, you can scale and rotate the sample source to clone the sample at a specific size and orientation. If you need to paint in a very specific location relative to the sampling point, you can use the x and y pixel offset.

Working with 3D Files
PS 7.4
Photoshop CS3 Extended includes support for 3-Dimensional (3D) files (New!) (.u3d, .3ds, .obj, .kms, and Collada file formats) created by programs like Adobe Acrobat 3D Version 8, 3D Studio Max, Alias, Maya, and Google Earth.
Opening 3D Files
You can open 3D files into a new document or insert 3D files into an existing document in Photoshop. When you open a 3D file, Photoshop asks you to set the height and width and then it places the 3D model on a separate 3D layer. The height and width you set scales the 3D model to your exact specifications without losing any detail or quality. If the 3D file also contains a texture, the texture appears on another separate layer. You can add multiple 3D layers to an image. To add a 3D layer, click the Layer menu, point to 3D Layer, click New Layer From 3D File, select a 3D file, and then click Open.
If your Photoshop document contains one or more 2D layers (typical images), you can combine any one of them with a 3D layer, or convert a 3D layer to a 2D layer. To add a 3D layer to an image, drag the 3D layer from one Layers palette to another, double-click the 3D layer in the new location, and then use the 3D tools to position or scale the 3D model.
Working with 3D Files
After you have opened a 3D file or created a new 3D layer from a 3D, you can use Photoshop 3D tools to move or scale the 3D model, change the camera view, change the lighting (such as daylight or interior light), or change render modes (such as solid or wireframe). If you have a texture layer, you can edit it using standard Photoshop tools and reapply the texture to the 3D model. However, you cannot change how the texture is reapplied or create a new one in Photoshop.
Edit a 3D Model
Double-click the 3D layer thumbnail in the Layers palette to display 3D tools on the Options bar.
Use the following instructions to perform the task you want:
- Move, rotate, or scale. Click Edit the 3D Object on the Options bar, click a navigation tool, and then drag to change the rotate, roll, drag, slide, or scale.
- Camera. Click Edit the 3D Camera on the Options bar, click a camera editing tool, and then drag to change the orbit, roll, pan, walk, or zoom.
- Lighting effects. Click the Lighting and Appearance Settings icon, and then select the lighting mode you want.
- Render effects. Click the Lighting and Appearance Settings icon, and then select the render mode you want: Bounding Box, Transparent, Line Illustration, Solid Outline, Wireframe/ Shaded Wireframe, Hidden Wireframe, or Vertices.
- View cross sections. Click the Cross Section Settings icon, select Enable Cross Section, and then select the option you want: Alignment, Position and Orientation, or Flip.
- View 3D animations. Click the Layer menu, point to 3D Layer, click Transform 3D Model, and then use the playback buttons.
To leave 3D transform mode, click Cancel 3D Transform or Commit 3D Transform on the Options bar.
