RAW Power unlocks the power of Apple's RAW engine with simple, easy-to-use controls. Use it as an editing extension inside Apple Photos, or as a standalone, non-destructive RAW photo editor. If you loved Aperture's advanced RAW processing adjustments, you'll feel right at home with RAW Power. Using adjustments like Boost, previously only available in Aperture, you can improve your images in ways that simply can't be done in any other application. RAW Power takes advantage of RAW processing improvements in macOS Sierra.
Note: The downloadable demo is version 2.1.1; the version available for purchase on the Mac App Store is version 2.1.2..
