Adobe has just pushed out an updated Photoshop Touch app for both iOS and Android, hitting version 1.3. The iOS version now includes Retina display support for the third generation 'new iPad', as well as support for print-resolution images up to 12 megapixels with up to 16 layers.

The new app also includes two new effects, a new three-finger tap, support for Apple's Photo Stream and smoother performance in the organizer, tutorial browser and file picker. Also included is a new "pixel nudging" mode for more precise movements.

The new three-finger tap feature will let you toggle between 100% view and "fit screen" view, while the two new effects added are called "Shred" and "Colorize". With the new version 1.3 of Photoshop Touch now supporting 12-megapixel images (only 10-megapixel on the iPad 2), users will need to change to the higher capacity in preferences, as the default value is still 4.2-megapixel with 10 layers.

Photoshop Touch is available for iOS through the iTunes Store, and Android through the Play Store.
