The "Extended" version included everything in the standard CS3 edition plus several high-end tools:

The first thing Sarah noticed when she opened Photoshop CS3 Extended was the intuitive interface. She was able to easily navigate the various tools and features, and she was impressed by the sheer power and flexibility of the software.

Because Adobe killed the activation servers, some users argue CS3 is abandonware. Legally, it is not. You still need a valid serial number. However, for historical and educational purposes, museums and archives often maintain CS3 Extended rigs to preserve 3D art created in that era.

Next, Sarah turned her attention to the animation tools in CS3 Extended. She created a short animation of a sunset, using the software's advanced timeline features to control the movement of the sun and the clouds. The result was a stunning and highly realistic animation that she was able to share with her clients.
