Description:
If you work with 3D, Photoshop Extended is a must-have upgrade; ditto if you think you should use more tools if the interface standard was less opaque, if you need to update application suite others, or if you qualify for an academic discount. All things considered, while Adobe Photoshop CS4 makes some improvements over CS3, it might be useful to skip this and wait for the next generation. There is just enough that it's better in the updates to Photoshop CS4 and Photoshop Extended - most notably, usability improvements for core features - that many people will find themselves sighing, biting the bullet, and upgrading.
If you work with video or 3D, or if you want to update your Creative Suite CS4 for other reasons, it is obvious, for the rest of us, there is little you can do with CS4 that you could not do with CS3, and the second seems a bit faster and more memory efficient in some respects.Photoshop CS4 Extended users will benefit more immediately from these underlying changes than ordinary users. In the second OpenGL support primarily manifests itself as some whizzy screen zooming and rotation tools, demos well, but probably will not get used much. However, Adobe has improved 3D support has been extended. It now offers most of the essential to make the settings and view controls, and the ability to create primitives (and extend the library of primitives), with the need for 3D models.
You can edit and paint on textures simply by double-clicking in the Layers palette, so you can see the changes applied when you change the model, not just in real time, interactive painting, but close enough to the time. And now it's basic keyframe animation in 3D scenes. Still room for improvement: we need better management of lighting and the ability to tile and more easily position textures, and in many respects, the user interface, such as the Rendering Options, are still far too dialog engine. And Photoshop gets very slow when you load (or generate via the Mesh from grayscale command) relatively complex models with tens of thousands of polygons.
