The Adobe Photoshop Touch allows you to create images with simple finger gestures. Easily combine multiple photos into layered images, edit them, add professional effects, and easily share from your tablet. Currently, Photoshop Touch runs on the Android OS, but Adobe plans an iOS release soon so you can run it on the iPad 2.
It supports extracting a subject from its background, layers, filter effects, and social sharing. You can share your images to Facebook and view comments right within the app.
With Photoshop Touch, you can start to sketch an idea in the field, then sync your files with Adobe Creative Cloud so they’re available for further editing in Photoshop.
