Last year, Adobe released Photoshop Touch on Android and have just now released the long-awaited iPad version. First and foremost, Photoshop Touch is an iPad 2-exclusive, meaning it will not work on the original iPad.
The app supports Photoshop layers, one of the most basic and most used Photoshop features, as well as simple finger gestures, allowing users to combine multiple photos into layered images, make edits, and apply professional effects.
Also included is the tablet-exclusive 'Scribble Selection Tool' which lets you extract objects in an image by simply scribbling on what to keep and then what to remove. With Refine Edge technology from Adobe Photoshop, even hard-to-select areas with soft edges, such as hair, are easily captured when making selections.
Creative Cloud support is built in, and lets you seamlessly sync your Photoshop files between your desktop and iPad. Social networking also gets a mention, with Facebook and e-mail sharing supported. You can also import images from Facebook, Google Image Search, and your iPad's camera roll. Photoshop Touch as I mentioned before, only works on the iPad 2, and iOS 5.
One huge benefit, is that it's only $9.99.
