DxO PhotoLab is a desktop photo editor for photographers who work with RAW files. It runs as a standalone application without a catalogue import and includes a library panel for browsing folders. Its DeepPRIME noise reduction uses machine learning and is applied while the RAW file is demosaiced; variants such as DeepPRIME XD3 target high-ISO files and Fujifilm X-Trans sensors. Lens corrections use profiles that DxO develops in its own laboratories for specific camera and lens combinations, correcting distortion, chromatic aberration and vignetting. Missing profiles are downloaded automatically.
DxO Labs is a privately owned company headquartered in Paris, France, with its founder listed as owner and chief executive. No non-EU parent company is involved, so the vendor operates under EU jurisdiction. PhotoLab is proprietary software, not open source. As a standalone desktop application, editing takes place on your own computer rather than in a vendor cloud, which keeps image data under your control.
