|The Looking Glass|
The Chrome extension allows you to view Facebook's "3D Photos", a feature they added in 2018 for displaying photos that include a depth map like those from phones with dual cameras, such as Apple's "Portrait Mode".
Getting StartedTo use the extension, connect your Looking Glass to your computer, navigate to Facebook and open the viewer from the extension's popup menu. This will open a browser window on the Looking Glass display's screen in fullscreen mode.
|Opening the Viewer|
The extension allows you to navigate through the 3D photos that have been found in two ways, controls just below the Looking Glass display and controls within the extensions pop-up menu.
The navigation controls within the popup menu show you how many photos have been loaded and which photo you currently viewer. The left and right arrow buttons allow you to navigate through the list, and the slider allows you to adjust the focal plane of the image. With the slider you can move into or out of the image, also known as dollying.

Along with the in-browser navigation controls, you can also directly manipulate the photos using the buttons on the Looking Glass. The square and circle buttons allow you to dolly out of and into the photo, respectively. And the left and right buttons allow for navigating through the list of photos.
