You can go a step further and use breezewiki, which is basically a wrapper for Fandom that disables all the annoying crap.
On any fandom wiki you should be able to just change the url from (...)fandom.com/(...) to (...)antifandom.com/(...) and load that page through breezewiki.
I've been using both Open Camera and PhotonCamera for a while now, and these two are probably the best options. You can get them both on F-Droid.
Do be careful with Photon, though, as its still early in development and is very crash happy (not to mention its development is extremely slow, maybe even dead at this point?). It also has network permissions for.. some reason, so make sure to disable those if possible.
Photon's image processing also sucks up your battery power quite a lot - one time I've seen my battery drop 2% just from taking a single image (I run a Xiaomi Mi 10T Pro with LineageOS)
Photon also lacks A LOT in terms of customization. It's also locked to taking pictures in HDR, unless you set the frame count to 1, in which case it will start taking pictures in RAW, which is even worse. It's also impossible to switch the directory where the pictures are saved, and HDR pictures and RAW pictures are stored in entirely separate folders.
Despite all that, the pictures that come out of Photon are definitely a grade above those I take with Open Camera, though I still use OC when I get fed up with Photon every now and then. And when set up right, the pictures taken with OC can be just as good.
Didn't see Receiver 2 mentioned, so I'll give it a shoutout! Really interesting game, and as far as I know the only one with such deep shooting mechanics. Unfortunately the sale had ended a couple days ago, so it's back to its normal price, but even then I'd heavily recommend it!
