If you’re like most photographers, you use Adobe’s Lightroom software to manage your photos. And if you’re like most photographers, you probably also use the sync feature to keep your photos in sync with your computer. But what exactly is sync, and how do you turn it on? Sync is a feature in Lightroom that lets you keep your photos in sync with your computer. When you first install Lightroom, it creates a “local” copy of all the photos on your hard drive. Whenever you add or delete photos from your hard drive, Lightroom updates the local copy of those photos automatically. This means that if you have a lot of photos on your hard drive, and want to make sure they all stay in sync, adding them all to Lightroom’s local copy can be a slow process. That’s where sync comes in handy: by default, it keeps a “remote” copy of all the photos on Adobe’s servers. Whenever you make changes to any of the photos on Adobe’s servers (for example, when you add them to an online photo album), those changes are automatically reflected in the remote copies of those photos that are currently syncing with other people’s computers. So how do you turn on sync? The easiest way is to go to Lightroom’s Preferences window (Window > Preferences), and click the Sync button next to the Local Folder field (see Figure 1).
