That's just the iPhone's default JPEG processing. You can avoid that by shooting RAW. I posted a comparison in this comment: https://news.ycombinator.com/item?id=27769511 https://news.ycombinator.com/item?id=27769511
Not sure what is going on with your comparison crop. The phone photo seems to actually be out of focus in the relevant area, not to mention overexposed.
- willis936 5y agoTechnically, iPhones use HEIF, which uses HEVC, which uses DCT and DST and variable block sizes. JPEG uses DCT with fixed block sizes. The results of the two file formats are similar.
- foldr 5y agoYes, sure. I mean that it's the result of sharpening, noise reduction, and the other processes that are typically applied to a raw image.
