Setapp is killing it lately. They just added Detail to the mountain of macOS apps coming with the subscription.
Detail adds a virtual multi-POV camera to your Mac — based on the built-in camera, your iPhone cam, maybe a connected DSLR etc. Plus it comes with automatic face tracking. And you can set up scenes and overlays and whatnot. It’s been a joy so far. Sadly, it can’t be used for FaceTime but then again, Google Meet is 90% of my calls these days anyways.
