So the question is really simple. I am using Photos app on my mac, without the knickknacks like Photo Stream, iCloud etc. The exact location of photos is the default one: /users/xxx/Pictures/Photos Library/Masters.
I have deleted some photos directly from the Masters folder in Finder, then also from the trash. Yet I still see these photos in Photos app. When I go to Finder again the photos are not there anymore. How come are these photos still displayed in Photos? Are they cached somewhere? Even a restart still shows me those.
