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:

As you can see, not a whole lot of transformation is require to yield exciting results

For it's actual purpose (chromatic aberration) the set up works fantastically.

Left: Standard R, G, B split. Right: Spectralized

Especially apparent at higher intensities

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.
