Let's start with the main camera, which has sadly prompted Samsung to revert to an old negative habit. Images from the main camera oftentimes come out excessively sharpened. While the rendering of buildings, objects, or people are moderately oversharpened to the point of making fine detail stand out, the sharpening algorithm really goes overboard with any foliage and grass that happens to be in the frame. Things look fine at fit-to-screen level, but zoom in closer or, better yet, look at the photos on a monitor, and the overdone sharpening becomes obvious.
Worse yet, we can notice a clear difference between our Galaxy S23 Ultra photos from the
camera comparison we did back in March and the phone's photos today. The main camera images were sharper than average back then but are way oversharpened now, to the point that you can see a halo at the edge where the trees meet the sky in the shots below.
