Great news for Lightroom users on Android: Adobe has just updated the app to version 2.0, introducing an in-app camera with DNG raw file capture, shoot-through non-destructive presets, split toning, and more.

Those looking for a more complete mobile photography solution that allows one to take advantage of the latitude inherent in raw files will want to give the new version of Lightroom a try. Adobe has given the app a major overhaul, introducing many new features:

• In-app capture with DNG raw file support
• Nondestructive presets with real-time shooting previews
• Split toning capabilities
• Point curve mode in Tone Curve tool, with access to individual color channels
• Dehazing capabilities
• Targeted Adjustment Tool, which allows for tuning of colors in specific areas of a photo
• Video creation in tandem with Adobe Premiere Clip

As mobile platforms become more and more powerful, it's great to see raw capture and editing abilities being augmented. Photographers who are on the go and constantly looking to provide instant content will appreciate the fine-tuning possibilities that come with raw capture and editing. I personally use Photoshop Express as part of my mobile workflow, but alas, the walled garden of Apple does not allow the user access to true raw files. Check out some before and after edits (taken by Colby Brown) from the new app below.

"the walled garden of Apple does not allow the user access to true raw files".

This is incorrect. You can store RAW files on Apple mobile devices; and you can edit those RAW files with certain applications (e.g. Photogene, Snapseed). It is true that Photoshop Express does not handle RAW files; but that was an Adobe design decision based on how they expect your workflow to integrate; nothing to do with Apple.

Personally I use an iPad for temporary storage of RAW files when travelling; but editing these files on a mobile device doesn't appeal.
