Last April, Adobe released the powerful Creative Suite 5.5 and the Photoshop Software Development Kit(SDK). The Photoshop Touch SDK and a new script capability in the updated Photoshop CS5.1 offer developers the tools to design applications that interact between the touchscreen device and Adobe Photoshop. To herald this event, Adobe released three apps for the iPad: Adobe Eazel, Adobe Nav, and Adobe Color Lava. Each of the three apps can interact with Photoshop CS5 or CS5.1. They are not compatible with earlier versions of Adobe Photoshop.
