Free Raw photo-processing software RawTherapee has been updated to version 5.5, gaining a new Shadows/Highlights tool, a striping and banding tool, unbounded processing and numerous other updates. In addition to the new features, RawTherapee 5.5 brings a number of bug fixes, feature improvements, and speed enhancements.

RawTherapee 5.5 includes a Haze Removal tool that strips haze from images and a new Soft Light tool for boosting saturation and contrast in images. The old Shadows/Highlights tool was removed and replaced with an updated version and users now have Grid and Regions color toning options. The main histogram has three scaling methods now as well, and there's a new Flexible tone curve type.

RawTherapee 5.5's new artifact filter removes the striping artifacts that result from Sony's Phase Detection Auto Focus, as well as the banding artifacts resulting from Nikon's in-camera PDAF correction. At this time, the filter supports the Nikon Z6 / Z7 and the following eight Sony cameras:

  • Sony DSC-RX1RM2
  • Sony ILCE-6000
  • Sony ILCE-6300
  • Sony ILCE-6500
  • Sony ILCE-7M3
  • Sony ILCE-7RM2
  • Sony ILCE-7RM3
  • Sony ILCE-9

As always, RawTherapee is free to download on Mac, Windows, and Linux. The full v5.5 changelog detailing the new features and improvements is available here.
