1. Open up Adobe After Effects and import a photo file into the program by right-clicking in the “Project” window and selecting “Import” then “Files…”. Choose any type of photo, or a specific one that you plan to use for a future project.

2. Drag the object into the “Timeline” window below. Change the composition size so that the object fits well into the screen. You can do this by right-clicking in the “Timeline” window, selecting “Composition Settings” and choosing a pre-set format size.

3. Click on the arrow to the left of the file name in the “Timeline” Window. Click on the “Transform” arrow and locate the section that says “Scale”. It will usually be the third choice under the transform options.

4. Click and drag any of the percentages that are listed to the right of the “Scale” option. In the preview monitor, you will see your picture growing or shrinking.

5. Choose the starting point of the scale that you wish to choose. Press the picture of the small clock next to the word “Scale” to start the key frames.
