Adobe has released a newly rebranded mobile version of their Adobe Photoshop software for iPhone and iPad. The app, named Adobe Photoshop Express is a free to download utility available from the iTunes App Store that will provide all the basic photo editing features that will one will require on the move. Of course, this application is a far cry from the comprehensive list of features that you may access from the actual Photoshop software, it is still a good app if you want to adjust color, crop, rotate pictures, etc.
Though this is a universal iOS app, there are a few features unique to the iPad including those like the ability to edit multiple photos at any given time and also to work on pictures in both landscape and portrait mode. Also, the app does not include support for the retina display on the new iPhone 4. But you should expect them to become available shortly.
