What this is
Spectral transition splits each picture into bands, from broad shapes to fine texture, and swaps the bands one at a time. The pyramid method makes the bands from blurred copies of the picture; the Fourier method makes them from rings in its Fourier transform.
How to use it
- Tap the image to cross the two images.
- Pick a method and which bands lead, then set the stagger 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.
