Standalone lens profiles for use by Adobe ACR/Lightroom, Rawtherapee, and others may or may not use the correction factors from the official tools, but if they work.they work.
If the corrections are recorded as enabled, those two tools will apply the corrections as part of the default processing. Well, I have just on camera (KP), which allows shooting in the PS mode, and I might to try it just for later color removal (well, to get similar results as from the K3/III Mono camera).
#Rawtherapee lens correction windows#
RawTherapee and other open-source projects require access to sample raw files from various camera makes and models in order to support those raw formats correctly. Accidentally I've encountered this 'open source' photo editor, with many features aimed towards the Pentax PS improvements. RawTherapee 5.8 has been released Windows Build Repackaged We found an issue with the original 5.8 Windows installer, it was missing the Profiled Lens Correction (Lensfun) database, so there is now a new installer from which includes this database.
#Rawtherapee lens correction software#
Components are as below:ĭiffractionCorrection: on/offThere are corresponding entries in the "Shooting Information" panel in the Pentax DCU software and as far as I know, that software and the camera firmware are the only means to apply the "official" correction factors for a specific lens. Hundreds of bug fixes, speed optimizations and raw format support improvements. These are found grouped together at the same address in Makernote and have been given the tag name LensCorr by the ExifTool team. With that tab selected there is a tool called Digital Lens Optimizer that appears to. RawTherapee will search through the files in the 'Flat-fields directory' specified in preferences and select the exact or, if not available, the closest match to the image being corrected based on camera make, model, lens, focal length, aperture and date of the flat-field file. Actual correction factors appear to not be stored rather, it is what correction features were turned on when the exposure was made. DPP4 has a tab in the editor called Perform image lens correction.
It doesn't seem to be able to read it off the RAW file itself.I dive into the Pentax Makernote interpretations used by ExifTool ( LINK) on a fairly regular basis and the developers of that tool have been able to find and characterize a fairly limited amount of data associated the lens correction feature.
