Compatible with Adobe Photoshop CS3, Photoshop Action Pack includes 85 Actions for Automator that allow users to automate virtually all Photoshop functions using Apple’s Automator technology.
On the other hand, the new collection is basically a maintenance update that offers improved rendering when using the Save for the web features. In version 3.5, the Save for Web feature provided images with a washed out look. This has been fixed in the new version.
The new collection also includes a completely redesigned Render action that requires less space in the workflow window, thus making navigation easier.
Automator’s new action, Strip Extra Channels, removes all extra channels from a document leaving only the color channels that are relevant to the document’s color mode.
The Photoshop Action Pack is available as a free download, although donations are accepted by the author.
