The finishing touch against color fringes
What is it about?
Sometimes the technical correction in the RAW module (“Raw Chromatic Aberrations”) is not enough. Especially with older lenses or extreme contrasts, stubborn purple or green fringes remain. This module is the second line of defense.
The difference to the RAW module:
While the RAW module tries to physically shift the color channels over each other, this module works more like an intelligent filter. It specifically looks for typical colors of color fringes (purple/green) at edges and desaturates or recolors them.
How to apply it:
- Activate the module if you still see color fringes despite RAW correction.
- Often, simply turning it on is enough.
- If not, you can adjust the thresholds to tell the module exactly what should be recognized as a “color fringe”.
When to use?
Only when needed. If the image looks clean, leave it off.
