Resurrect the Extract Command
The Extract command is no longer offered in Photoshop CS4, but you can still access its functionality in the new version of Photo-shop by transferring a file called ‘Extract-Plus.plugin’ from the Plug-Ins>Filters folder of Photoshop CS3 to the same folder in Photoshop CS4. It works ?ne and hopefully, there’ll be something even better in CS5.
