cf_spectralize

Updated: Aug 10, 2020



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.

Hey Chris! Love your work!


I've tried this in the recent Nuke version and unfortunately the tool seems to be broken. Would you be able to make an updated version of the tool? Thanks!
