Fringe killer usage

Post by mgutierrez »

Hi all,

I'm trying to remove chromatic aberration from some stars. Fringe killer works nice but leaves a grayish background color where I apply the filter:

any tips?

The Finge Killer indeed leaves the luminance (detail) intact and only attacks the color.

A few different techniques;
  • You could try the Shrink module on those stars, with Color Taming increased.
  • If your blue channel is very poor, you could also decide not to use it for luminance at all; use the Compose module to create a synthetic luminance frame from just red and green (set blue exposure to 0).
  • You can also use the FilmDev module to throttle the blue channel's luminance contribution before using the Filter module.
Hope this helps!

Another option is to select all the problematic stars and exclude them from the colour module so they stay as just luminance.
