"Unsurprisingly, Photoshop Touch doesn't offer the same level of flexibility as the full desktop version, but its feature set is impressively 'deep' nonetheless, and includes support for layers, a decent array of familiar Photoshop selection tools, effects and filters. Also available is a range of image acquisition options including synching to Adobe’s Creative Cloud, Facebook and Google Images.
When images are opened they are converted in the app to a psdx layer format. When exported to Facebook, saved to the tablet, or emailed they're converted to the JPEG file format, at a maximum output resolution of 1600 pixels (along the longest edge). When exported to Adobe's Creative Cloud, the file remains a psdx file and can be opened in Photoshop CS5 using a free plugin, and then saved in any format (although the 1600 pixel limit still applies).
The 1600 pixel limit is disappointing, but at least - unlike the earlier Photoshop Express app - zooming to 100% is possible, and very easy using the now-standard 'pinch apart' gesture. With a restricted workspace Adobe has done well to keep the UI as streamlined as possible - a familiar tool palette arranged vertically down the left-hand side can be minimized to make best use of the screen’s real estate while a menu bar along the top features more tools and drop-down windows for adjustments and effects.
