The latest iPhones perform better than ever in low light conditions but to capture great selfies at night, you are still going to need a light source. The Kodak x Lumee Dual Light iPhone 11 case can help. It comes with front and rear illumination.
The lights on the case balance out even back light. They are great for shooting photos and video. The LuMee Duo iPhone 11 case runs for 30 minutes on battery.[where to get it]
