The above picture of the C&NW engines was taken with my iPhone XR and is in JPEG format and is a 3.4MB size file. The APPLE HEIF (compressed) file would be about 1/10 of that size. I suspect that 95% of all Apple iPhone users that take pictures are doing so to upload them to social media websites or email/text them to friends. They probably couldn't care less about "quality". Apple is probably doing most iPhones users a favor since most users are on limited data plans and/or running out of space on their phones. All major social media sites can handle the new Apple picture format. The iPhone X series and iPhone 11 series have nice resolution cameras and take great pictures but do create larger size files using JPEG format.
