RAW Power

according to a comment from 2017, this priced $10. Now $40. The magical word "raw-power" means nothing. Been on Developer's website. GraphicConverter does everything and much more that RP.

I'm using Raw Power on both macOS (Catalina on an old 27" iMac 2013, but it's very stable), and iPadOS (iPad Pro 2020 12.9). Having migrated to Photos from Lightroom after going over to using an iPad Pro, Raw Power has become my Goto editing app. It integrates superbly with Photos, and keeps all its non-destructive edits within the Photos ecosystem, so it synchronises with any device you have RP installed on, and can carry out editing on any of them. It is fairly basic, but initially that's all I need, get a starting point, easily and seamlessly with my Photos library. It does that better than any other app out there. It also adds a few improvements to Photos library management too, such as star ratings, and can also be used to manage folders and albums, so you might not need to open Photos itself very often. It's actively developed with new and improved updates coming all the time, and the developer is very responsive to suggestions and bug reports. Of course there are other options (in reply to previous reviewer), but RPP hasn't seen a full release since 2014, although there's a few discussions on Google Groups, it's unclear what its future support is like. Most other options can break the non-destructive workflow, use very large external sidecar files, or are considerably more costly. Affinity, as an example creates a 250MB file from a 25MB NEF file. Of course we all have different needs and preferences for our photo editing and management. Overall though, Raw Power is an excellent app for basic editing and management of your Photos collection.

=== the good: nice-looking GUI, good workflow, good-enough-perfomance, ApplePhotos Extension - - - - === the bad: many crashes (Apple M1 & BigSur) - - - === the ugly: poor results (not really good as Apple Photos - crazy, because it's the same raw engine!), destroy highlights and shadows (!) - - - === download Iridient Developer ($99) or Raw Photo Processor ($25 Shareware) and you will delete RAW Power - immediately!

Instantly a part of my workflow. Intuitive to use and very handy that it works independently as well as in Photos as a plug-in. Will be interested to see what an update brings to the table.

For $9.99, you can't really lose out on a product that brings back some of the raw editing functionality of Aperture (among others), supports DNG and is both fast an intuitive. I had a few questions for the developer about color spaces and got a reply within an hour of sending an email. So that's a very good sign!
