Open F-Droid, search camera. I see Fossify Camera, Open Camera, Libre Camera, and FreeDCam that basically provide the appeal that this subscription camera app has (AI-less).
Open PlayStore/Alternative, search camera. Holy cow! I'm not even going to name any. There are so many. Not all are AI-less, but there are a plenty.
Also, GCam has a RAW option. So.... out of the box, this new camera app is unnecessary.
Why would you make the picture worse on purpose? The cameras of modern phones have their own Algorithm chip to enhance the image as the actual camera isn't really that capable.
Overall Google does impressive processing of photos. But for a while, photos with my Pixel were visible "over-processed" looking. It's improved now. But it still goes to far making the sky look colorful sometimes.
It's good to have the option to do my own processing, or just to take a picture as-is as much as possible.
