Effect
What this is
Lumen light treats the picture as a scene full of fine haze. Light scattered by the haze draws visible shafts, the Tyndall effect, and in the burn and backlit modes that light carries the first image over into the second.
How to use it
- Tap the image to play the light.
- Choose a light mode, then move the light and set the haze with the sliders.
- Swap in your own two images, then save a PNG or record a video.

Common questions
Where do my pictures go?
Nowhere. They are opened in your browser and drawn on your graphics card. Nothing is uploaded. The pictures you add stay on this device, in this browser, so the other lab tools can open them too; × on a picture removes it.
