ON1 Photo RAW is a relative newcomer to the photo editing arena (currently designated ON1 Photo RAW 2021.5), but looks to be feature filled. It includes Digital asset management and a non-destructive, layered editing paradigm, incorporating many features of photoshop as well as Lightroom. It comes with either a one-off license or a subscription model that allows you continued updates as the software develops. They offer a 14 day free trial.
According to their website, ON1 can import Lightroom settings from existing LR catalogs (at least this is scheduled for the October 2021 release). It has photo-retouching tools, cloning, healing, removing blemishes, noise reduction, content aware fill etc. It handles HDR, focus stacking and panoramas. It uses some AI approaches to aspects of its image processing. It can also operate as a plugin for Adobe, Affinity and Corel applications.
On1 has a few specialised features. Notable is an AI powered portrait editing mode that looks to be quite powerful. It automatically identifies features like lips, eyes, eyebrows etc and provides controls to adjust their appearance. You can also modify the shapes and sizes of the face or face parts. If you do lots of portraiture it is definitely worth a look.
