The well-known YouTuber emkwan was one of the first reviewers to get the iPhone 12, and he also tested the "better low-light photos" emphasized by Apple at the press conference with the new machine, comparing it with the night mode of the iPhone 11 Below, you can indeed find that the new machine is better in the details of the dark part of the photo.
Through the photos taken by emkwan , it is not difficult to find that the details of the dark parts of the photos are more prominent in the night mode of the iPhone 12. According to Apple, this is because the lens uses a larger aperture than before, so the new wide-angle camera can capture a 27% increase in light.
In addition to the dark details, you can also find that the overall photo saturation is higher. Of course, this may be a parameter setting problem. And through these two photos, it proves that the iPhone 12 is better in capturing the details of the dark parts, which means that the photographer will have a higher degree of freedom in post-production.
