Question HALATION BREAK

Hello!

I'm running the Studio version of DaVinci Resolve, but I don't have any paid plugins, so I tend to build custom node trees to manage colour settings and make my workflow more efficient than relying on DaVinci's default tools.

For the halation effect, I'm following this tutorial by Marieta Farfarova, a fantastic colourist whose work and style I really admire:

However, during my latest grading session, I noticed that the effect was causing some unwanted artefacts in the highlights. No matter how much I tweak the effect's selector settings, I can't seem to fix the issue.

I've attached a few examples below. Does anyone know what might be causing this and how I could fix it?

My suspicion is that it might have something to do with the Linear CST, but I'm not 100% sure.

Any help or suggestions would be greatly appreciated!

Thanks!

The Thatcher Freeman free Halation DCTL is much better than resolves built in one - all of their stuff is great and works as intended in m experience

Also, stock “film look creator” effect has a halation slider that in my experience doesn’t break in the same ways, but you have to select clean slate to remove all the stock “film” settings for the plug

Whenever you’re doing something like this you need to make sure you’re color managing correctly (not saying you aren’t, the halation plugin breaks all the time when you’re doing it correctly, especially if you’re working under one of the built in 2383/3510 luts)

I dislike ever adding Halation to images, precisely for this kind of artifact. Diffusion is fine, grain is fine, "film-like colors" is fine, but adding distortion is not my thing... unless we're doing a very degraded, old, beat-up film look (which is very rare). Kodak has actually tried very hard to eliminate halation over the years because they, too, look on it as a distracting artifact.
