POST PROCESSING ON IMAGES

I have noticed that everytime i take a picture using iphone 13 pro max, the image that is saved is darker than the one i took (what i saw while taking the picture). I don’t like this post processing, so how do i turn it off?

And no it is not related to HDR or live photos or the lens correction feature or any other “solution” i’ve seen on here. They all don’t work. I really HATE this feature/setting. Could someone please help me?
