To be up front, editing raw files on the iPad isn’t yet ideal. Or, if your images need only minor tonal or color saturation adjustments, they may benefit just from a pass through a raw editor without any further processing. Then, after exporting the file (as a JPEG), use Snapseed or Photogene to perform additional edits. If you’re working with a dark image, for example, running it through piRAWnha first may tease out detail that another editor might overlook.
These apps can act as preprocessors for a photo-similar to the way the Adobe Camera Raw plug-in works in Photoshop.
