I an kind of unhappy with the camera app on #GrapheneOS I am using on my Pixel phone. I tried the stock camera app as well as Open Camera. The images come out lacking in colors and clarity compared to what my older iPhone can do. 
5k sat zap for he who can recommended me a FOSS camera app or settings that make my photos look better than they do now. 
Seriously considering installing the Google camera app sandboxed.

 I just use the Google Camera for important photos. You can remove the network and location permission to prevent it from calling home and use some foss exif remover to remove metadata. I don't think gphotos uses steganography to track users :D
