Free Editing Software RawTherapee Adds Impressive ‘Capture Sharpening’ Feature

Free Lightroom alternative RawTherapee just released version 5.8. And in addition to the usual compatibility and performance improvements, the open source software has also added an impressive new feature called “Capture Sharpening.”

According to the release notes, Capture Sharpening specifically addresses detail that is lost to lens blur (AKA diffraction). “It takes place right after demosaicing, and as it works in linear space it is not prone to haloing,” reads the description. “Capture Sharpening in combination with Post-Resize Sharpening allows for detailed and crisp results.”

People who use RawTherapee as their raw photo editor of choice will tell you that it’s already phenomenal at sharpening, and this only makes it that much better. If you don’t need the cataloging or advanced masking tools available in Darktable, RawTherapee might be your open source Lightroom alternative of choice.

Here’s a sample screenshot of the feature in action (click to enlarge):

In addition to Capture Sharpening, v5.8 also features support for Canon’s CR3 format (though metadata is still not supported yet), speedups and optimizations to various tools, better memory management, and various bug fixes.
