Pentax K3 III Monochrome

Hi,

I am getting some ugly magenta rendition of Pentax K3 III Monochrome in RawTherapee. I’ve tried the Mono debayer mode and No Input Color profile, however to no avail. I’ve provided samples in late 2023 (Index of /data/Pentax/K-3 Mark III Monochrome) for a similar same issue in darktable.

Thank you advance for your support.

Best Regards,
John

Hi, I just opened your dng file, switched off white balance and turned on auto matched tone curve and this was the result.

Perhaps you didn’t turn white balance off?

What version of RT are you using?

Hi Nosle,

Thank you for your input. It was user error, I did not disable the white balance module. I read the Monochrome Cameras section under Demosaicing, but didn’t catch up the WB nuance.
