Lumiro is the best and fastest way, for you as a photographer, to set up your device for a hassle-free still life/promotion photo session. Select an image or a color and set the brightness of the screen and you are ready to go.
Regardless if the shoot is for social media or to create a mock-up its super easy and super fast. No more dark screens and/or smudges just because the screen turned off in the middle of the shoot.
Note:
This app is intended for photographers shooting still life images of their device with another camera.
