Modern smartphones depend heavily on computational photography to take high quality pictures. The reason you're not getting high quality pictures is because you aren't using HDR+. GrapheneOS does support HDR+ via the Pixel Visual Core in compatible apps set up in a supported way.

What camera app would you recommend to take advantage of the Pixel Visual Core? I cannot find the HDR+ option in the default GrapheneOS camera app on my Pixel 3 XL

Make sure to enable the Camera2 API and try following their instructions for using a mode compatible with the Pixel Visual Core in opencamera.sourceforge.io/help.html#faq. Avoid their legacy HDR support, it's a very obsolete approach with bad results and is something far different than HDR+.

Try building and using github.com/google/pixelvi. It should provide working HDR+ on the Pixel 2, Pixel 2 XL, Pixel 3 and Pixel 3 XL with GrapheneOS. I haven't tested it for a while though. You can check if it's working by watching the `adb logcat` output for relevant information.

HDR+ via the Pixel Visual Core is used automatically when apps use a compatible camera mode. It's meant to work for the default configuration in most apps. It doesn't work with AOSP Camera, but it should work with lots of other apps. They should fix their code if it doesn't too.
