What I don't get is why JPEG is still so commonly used when it introduces significant artifacting (even at high qualities). When a more advanced format like WebP can deliver higher quality images for the same file size.
From the article: "The app saves the raw frames captured from the sensor as DNG files, which can later be downloaded onto a PC for processing."
What does this have to do with the article?
The images in the article are JPEGs with visible compression artifacts which isn't good if they want to demonstrate the quality of the photos that they can make with the phone.
