The latest version of the popular open-source raw processor, Raw Therapee, adds new features, speed improvements and support for ten new cameras.

Released overnight, RawTherapee 5.5 includes filters to remove striping artefacts caused by Phase Detection Auto Focus (PDAF) in Sony cameras as well as banding artefacts caused by Nikon’s too-aggressive in-camera PDAF correction. Users also gain the ability to specify custom working colour spaces and decide whether out-of-gamut colours should be clipped. The Shadows/Highlights tool has been upgraded and a contrast threshold mask which divides an image into areas of high and low detail, allowing the effect of certain tools to be focused where it matters most enables tools like sharpening and demosaicing to be applied to in-focus subjects without affecting the out-of-focus background.

New colour toning methods allow toning to be applied separately to shadows and highlights or regions, based on a grid or any number of masks. The bundled ICC profiles have been re-generated, and now include ICC v2 and v4 variants. Support has been added for the Nikon Z6 and Z7 as well as the following Sony cameras: RX1RM2, ILCE-6000, ILCE-6300, ILCE-6500, ILCE-7M3, ILCE-7RM2, ILCE-7RM3 and ILCE-9.
