The DxO PhotoLab PhotoLibrary PhotoLab 5 adds IPTC metadata and keywords to its PhotoLibrary tools – but at heart it’s still a photo browser and not a full-blown image cataloguing tool like Lightroom or Capture One. These are separate add-ons described below in the review. The screenshots also show palettes and tools from DxO ViewPoint and FilmPack. PhotoLab 5 comes in two versions: Essential and Elite. Where Optics Pro was simply a RAW processing and lens correction tool, PhotoLab adds local adjustments to become a much more powerful photo editing tool.
