How To Use Adobe Photoshop CS2

Photoshop and ImageReady enable you to create impressive animation sequences using progressive applications of various texture filters or distortion filters. By creating duplicate layers of the same file and then applying a filter with increasing intensity, you can easily animate the filter application. In this task, we take a close-up image of a flower and apply the Motion Blur filter in successive layers to create a nifty animation. Although you can start with any type of file, animations must be saved in the GIF format.

1. Open the File

In Photoshop, select File, Open and select the file you want to animate with a filter.

2. Duplicate Layers

Select Window, Layers to open the Layers palette. Select Duplicate Layer from the palette menu multiple times to create several individual states for the animation. In this example, I created three more layers.

3. Filter the Layers

Select the first layer in the Layers palette and open the desired filter (for this example, I selected Filter, Blur, Motion Blur). Apply a modest filter amount and click OK. Select the other layers in sequence, applying the filter to each layer with increasing intensity.

4. Open the Animation Palette

Select Window, Animation to open the Animation palette.

5. Create Frames

Select New Frame from the Animation palette menu to create a new animation frame. Repeat this step to create a corresponding frame for each filtered layer you created in step 3. For example, if you have the original layer and created three filtered copies in step 3, create four animation frames now.

6. Assign Layers to Frames

With both the Layers and Animation palettes visible, click the first animation frame and select the corresponding first layer of the filter progression. Click the visibility icons (the eye icons) for all the other layers so that only the selected layer is visible. Then click the next animation frame and select the next filtered layer in the Layers palette, making sure that only the selected layer is visible. Continue until each frame is assigned to a layer.

How-To Hints

Using ImageReady if Necessary

If you have a pre-CS2 version of Photoshop, the Animation palette is available only from within ImageReady. However, Photoshop offers many more filter options than does ImageReady, so you still might want to perform steps 13 of this task in Photoshop. After you have filtered all the layers, click the Jump to button at the bottom of the toolbox to open the file in ImageReady and continue with step 4.

7. Play Back

Click the Play button at the bottom of the Animation palette to play the animation. Check for smoothness, alignment, and timing between frames. The animation will replay continuously; click the Stop button to stop the playback.

8. Set the Loop Count

The Loop Count option controls whether an animation plays once, forever, or a specific number of times. Select Once or Forever from the pop-up menu; alternatively, select Other and enter the number of repetitions in the dialog box that appears.

9. Set the Frame Timing

To add a timing delay for a single frame, click the timing pop-up menu underneath the frame you want to modify and select the desired time delay. For example, you might want to add a longer delay to the first frame to emphasize the original state of the image.

10. Launch Save for Web

Select File, Save for Web to open the Save for Web dialog box. Optimize the animation as a GIF file as explained in Task 2, "How to Build GIF Files for the Web."

11. Preview in a Browser

Click the Preview in Browser button. The animation file opens in the specified browser with information about the file size, file type, and compression type displayed at the bottom of the window.

12. Save As GIF

Configure the GIF format settings in the Optimize palette and select Save to save the GIF file. For details on how to save GIF files, refer to Task 2, "How to Build GIF Files for the Web."

How-To Hints

Optimizing and Saving Animation Files

If you are using ImageReady for your animation, remember to save the file as a GIF in step 12. Optimizing the file as a GIF in step 10 sets the number of colors and so on; it does not save the file. You must save the file using the GIF89a format; otherwise, the file will not animate.

Keeping the Number of Animation Frames to As Few As Possible

Animation frames dramatically increase file size and, consequently, download times. Keep the number of frames to a minimum to ensure fast download times and to guarantee fast-loading pages.

Animating Text with Warp Text

Consider using the Warp Text tool for sophisticated text animation. Create the text with the Type tool, build animation frames, and apply Warp Text effects gradually to each frame. Warp Text is an icon in the upper-right corner of the Options bar for the Text tool.
