When you press Mirror Luminar Neo from the Luminar Share app, you are prompted to open Luminar Neo and go to the Edit tab to start mirroring. When you do this, the current photo you are editing appears on your phone screen, with all edits made live as you work. This is a great option if you want to edit photos with your client side-by-side, letting them view the images on a phone or tablet as you edit them. This is also a great option to ensure color accuracy before you post an image to social media.
