It appears that quite a number of you want to know more about working with Lightroom and what tips might help save you some time. With this in mind I put together this short 10-minute video demonstrating a few points including History, Snapshots and Integration with Photoshop. These may not be the most exciting features but they could save you a lot of time. Probably much more than the 10 minutes it takes to watch the video.
As always, requests for future video topics are gratefully received.
