Hello Linux Geeksters. As you may know, Rawtherapee is an open-source image processing software (similar to Adobe Lightroom), written in C++ and using GTK+ as frontend. The latest version available is Rawtherapee 4.2, which has been recently released, coming with the below changes:
- RawTherapee-4.2 includes many speed, precision, stability and memory usage optimizations. As such, users of 32-bit operating systems may now find that they can enjoy more stability while using the most memory intensive tools. Of course users of 64-bit systems benefit from this as well. Refer to the full changelog for more information.
- Powerful color toning tool.
- Curve control of luminance noise reduction.
- Median filter in the noise reduction tool.
- Film simulation tool using Hald CLUT pattern files.
- Command-line option to define bit depth of output TIFF/PNG file.
- Multiple improvements to dead/hot pixel handling, see RawPedia.
- Filename of currently opened image shown in the titlebar.
- Clip control for the flat-field correction tool.
- Demosaic method “Mono” for monochrome cameras, and “None” for no demosaicing.
- Copy/paste processing profile keyboard shortcuts for right-handed users using Ctrl/Shift-Insert.
- Update to dcraw 9.22 1.467
