Overexposed areas get magenta outline

IMG_9713.CR2 (23.1 MB)

See light on the background in the middle of the image.
Whe I load it with “Default” profile I get while circles with magenta outline.
Guess it happens for a reason explained here: Visualizing the raw (sensor) highlight clipping | darktable

But how to fix that with RawTherapee? I tried changing HL Reconstruction settings, it didn’t help.
Positive (>1) Raw White-point correction helps somehow but worsens situation with other nearly overexposed areas to an unacceptable level.

JPEGs produced by camera itself are Ok.

Defringe in the Details toolbox pretty much fixes it.

In addition to the Defringe moule, I used the LH and CH curves in the LAB tab to reduce the chromaticity and increase the luminosity of purple. Have a look:

Using a DCP from Adobe DNG Converter and enabling Defringe, you beat the out-of-camera JPEG with minimal effort.
Canon EOS 700D.pp3 (9.4 KB)
Canon_EOS_700D_Adobe_Standard.dcp

Make sure that when you apply the PP3 that it picks up the DCP, so that in the Color Management > DCP section the checkboxes are enabled, as in my screenshot.

Neutral:

Canon EOS 700D.pp3

Then you can set this PP3 as your default PP3 for raw files.

Using sRGB as working space also helps for desaturating fringes :wink:

From now on DCP is apllied by default for every photo.
I have also installed newer RawTherapee with Defringe tool.
