Facebook was a pioneer in bringing virtual reality photography to the masses. By integrating 360-degree photos into the standard news feed, they allowed users to explore scenes from weddings, travel destinations, and real estate listings in an immersive way. However, the platform does not provide a native "download" button for these immersive images.
If you love a 360 photo, ask the creator. Most will happily share the original file if you credit them. download facebook 360 photo
