The complexities of Apple’s Photos.app

Since I have recently written about and recommended multiple Extensions for Apple’s Photos.app, I thought I would share a link to this article by the author of the RAW Power application on what happens “under the covers” when using an Extension. It also covers the difference between an Extension and the “Edit With..” functionality. What is happening is far more complex than you might imagine and will probably explain various inconsistent behaviours you may have observed.
