Accordingly, it has replaced 'clip highlights as the new default algorithm within the app. The new algorithms within the highlight reconstruction module are 'inpaint opposed' and 'segmentation based.' The former algorithm 'has proved very stable and provides good results in many images,' writes the darktable team. You can use the module to expand or condense the dynamic range of a scene to correspond to the dynamic range of a display. As outlined in the in-depth darktable 4.2.0 user manual, you use the Sigmoid display transform module to remap the tonal range of image using a generalized log-logistic curve.

Starting with the Sigmoid display transform module, this can be used in place of the existing filmic and base curve modules. Among the key additions are a Sigmoid display transform module, a pair of new algorithms within the highlight reconstruction module, a reworked pixelpipe for image display in the darkroom view, improved user interface, lens correction information being accessible from EXIF metadata, improved slideshow and more.

Darktable 4.2.0 is now available, adding new features to the open-source Raw image editing application.
