Last week I gave a talk to a room of photographers and showed some of my favourite Lightroom features. Not for the first time, the one that caused the most surprise was Develop's AutoSync mode - even among audience members who were already Lightroom enthusiasts.

Lightroom 3 Beta now has a little switch next to the Sync button which activates Auto Sync mode. It's a small change in the UI, and too subtle for some to notice, but at a stroke it will make this great feature much easier to discover - and will therefore make many LR users more productive. If you're not already using AutoSync, now's the time to catch up.
