If you have a Pixel and are willing to try GrapheneOS, you could also try their Camera app: https://github.com/GrapheneOS/Camera

There are builds of GCam which you can use as well, though if you don't want Google code on your device this isn't for you.

		If you're using GrapheneOS you can disable network access for GCam to reduce the risk that Google is spying on your photos. The postprocessing is notably better with GCam, so it's worth running on GrapheneOS imo.
