But the short version is: iPhone/iPad photos taken in Portrait mode contain depth information to be used to apply lens blur and lighting effects. I thought there was a lot of potential to use this depth information for other kinds of effects, so I made an app with a set of filters, most configurable with sliders, that you can apply to your Portraits. You can also save out the depth map or portrait effects matte to experiment with on your own. The app is free to use, but requires a small purchase to save photos.
You can try the app here: https://apps.apple.com/us/app/portrait-effects-studio/id6504...
Since I haven't yet localized the app for other languages, it's currently only available in the core Anglosphere (US, UK, Canada, Australia, and that island that gets left off a bunch of maps). I wanted to make it available in the EU, but I haven't been able to.
In addition to getting feedback, I'm happy to answer questions.
