How do I set dual capture on or off in Lumia Camera?

Dual capture is automatically on. This means that Lumia Camera stores both the 5MP photos and the full-resolution photos. If you don’t want to save the full-resolution photos, you can switch dual capture off. In Lumia Camera, tap  and settings. To switch dual capture on or off, change the setting for Capture mode.

Note: This applies to Lumia Camera in the Lumia 1020.
