RawTherapee 5.5 auto-matched tone curve very light?


On some files, the auto-matched tone returns a very bright image. Can others confirm this behavior, and if it is a bug I will file a report. The behavior is repeatable for me on certain images but never happens on others. Here is an example of what I am talking about.

And here is the SOOC


This does look unusual…



Is that from my PP3 or did you try independently?


Both. That is the auto-matched tone curve.


Would you consider it a bug or am I missing something here?

The part of the curve that descends left-to-right is inverting the tones in that range. The only valid use of such I’ve encountered was to invert a negative.

Have a look also here: Flat-Field correction & pattern noise, it might be already fixed. Apparently there were some ‘garbage’ pixels in the Fuji RAW’s that triggered this.

I also have some problems with the X-T2 files from time to time.

Seems to work fine on the latest dev version.


Awesome. Thanks
