Adobe announced today the release of Lightroom 5.4, which in addition to the typical bug fixes, new camera support and new lens profiles, includes an exciting new feature the ability to easily sync collections of photos to your iPad, where you can work on them and then have your work automatically sync back to Lightroom on your desktop. You can also view your synced collections of photos on private pages on the web at lightroom.adobe.com, and share them with others by providing them with the collection URL.
