Luminar is photo editing software from Skylum (née Macphun) that works as a standalone app, an Apple Photos extension or as a plugin for Aperture, Lightroom or Photoshop. Features include support for raw and PSD files, plug-ins and extensions; noise reduction and object-removal tools; layers, blend modes, and masking; brushes, filters and presets; batch processing and more, positioned as a subscription-free Lightroom alternative. (See FAQ and user guides for more details.)
Luminar 4.2.0 is priced at $138 (currently $89) with a 2-computer, cross-platform license for macOS 10.12 and up and Windows. A trial version installer is available in return for supplying an email address. The latest release includes “Face Features Detection Network, Shine Removal Technology, Slim Face 2.0 Technology”, etc.
Version 4 brought “several tools informed by extensive machine-learning” (apparently similar to Apple’s iPhone 11 image processing):
AI Structure in Luminar 4 automatically identifies objects like people and their faces, skin, sky, buildings and more, and improves them intelligently, instead of globally across the photograph. It adds detail and clarity to areas that otherwise wouldn’t have much, boosting the structure and making for a much more pleasing image. What this means is that instead of adding Structure to an entire photograph, it selectively does so, meaning photographers no longer have to mask or brush out the effect.
