Adobe’s update for Photoshop CS5 is officially called Photoshop 12.0.4 and it enables specially designed apps on tablets, smartphones, and PCs to communicate with and control interaction with Photoshop CS5 (Located in the File menu: Remote Connections).
Adobe says now you can be creative on other devices and instantly incorporate what you create into Photoshop. You must install the 12.0.4 update to activate a remote connection between Photoshop CS5 and any apps that Adobe or third-party developers create to interact with Photoshop. For example, Photoshop CS5 must be updated to 12.0.4 to interact with three new iPad apps that Adobe has designed to work with it – Adobe Nav, Adobe Color Lava, and Adobe Eazel. Available on the App Store.
The 12.0.4 update also fixes liquify performance, type related crashes, and other top customer issues.
