GrapheneOS uses our own camera app, not Open Camera. Our camera app supports HDR+ for images and HDRnet for videos on Pixels along with zoom-based multi-camera on devices with support for it in 3rd party apps including Pixels and current generation Samsung phones. It has Night, Portrait and HDR modes on Samsung phones. Pixels don't provide those CameraX extensions yet, but they provide HDR+ / HDRnet for it in the normal Camera and Video modes. Our app also supports optional EIS. It's not as featureful as Google Camera or Samsung's camera app but it's getting better, and you don't have to use it.
Google Camera works fine as a sandboxed app on GrapheneOS. You can install GSF as a regular sandboxed app alongside Google Camera and use it. Google Photos works fine too. You can disable the Network toggle for all 3 apps if you'd like.
https://grapheneos.org/usage#camera has more information on these topics, although it needs to be updated for recent improvements in our Camera app.
You don't need Play services or the Play Store for Google Camera, but you can use those as part of our sandboxed Google Play feature on GrapheneOS to run nearly all apps from the Play Store.
