cf_spectralize is probably the most visually dynamic tool I've made. Its brief was fairly basic: "Chris, do you think you could come up with a decent way of doing chromatic aberration for my lookDev turnarounds?"
It quickly grew from there.
The premise of the set up is pretty simple: Plug in 2 STMaps and an image, then cf_spectralize will iterate between the two transformations with a suitable rainbow inbetween.
It's how you manipulate the inputs that gives such dynamic results.
This quick demo shows what happens when you plug in a normal STMap to one input and a scale up version into the other.
After playing around a little bit with spherical transforms and other operations, the results rapidly became more and more psychadelic:
For it's actual purpose (chromatic aberration) the set up works fantastically.
To actually control the tool, simply set the step count and go!
If anyone wants to have a play around with the tool or has any questions, please do reach out to me.
