Users of Adobe's Android app have been able to process RAW images in the company's DNG format for a while, but the new update to v2.2 adds much more robust RAW processing. You can directly import RAW files from your camera, edit them, and export to all your devices.

Editing a RAW photo gives you much more freedom to tweak things like white balance, saturation, and exposure. Here's the full changelog for Lightroom v2.2.

  • Connect your camera directly to your Android device with a USB On-The-Go (OTG) cable.
  • Select your photos, and import directly into Lightroom for Android.
  • Then, easily sync your Lightroom photos with all of your other devices.

To get the full effect of this update, you need a USB OTG cable. When connected to your phone or tablet with Lightroom installed, you will be able to access the files on your camera using USB PTP mode. Adobe has a full list of supported cameras, which is huge. It's safe to say your camera is on the list if it is somewhat recent and takes RAW photos.
