No, I'm not being hard on anyone. People are here moaning and whining that they expected much better performance from a camera phone. People here are unwilling to accept any responsibility for the poor results they're getting. People here have totally unrealistic expectations backed by pretty much NO photographic skills. Does that mean people should be semi-pro or pro photographers? Of course not, but when it is clearly and simply explained things they can do to minimize or eliminate the flares, most seem to gloss over that and continue to complain that their phones are defective. They're not defective and that's my point. People need to learn how to use their cameras better and simply altering the angle of the camera, a beyond simple concept and thing to do couldn't honestly be easier.
I never said my photos are perfect. They're far from perfect. But they do appear to be better than many of the awfully photographed pictures people keep posting as evidence of a defective camera system. What people keep posting is poorly photographed photos. Actually, some of the photos are actually not bad, they just didn't do anything to avoid flares. It's not something they're accustomed to doing, because this may well be first ever camera system they've ever used, which can take a clear photo in darkness. The reference to "my iPhone 8 didn't do this" is a poor reference. iPhone 8 couldn't take a photo in low light with the resolution iPhone 12 is capable of taking. And so, people are shooting more photos in low lit situations at bright lights, which are being rendered with flares - a naturally occurring artifact. An artifact with some care can be eliminated. Or an artifact which will continue to be present in low light photos when no care is given to doing anything to eliminate them.
Finally, if your rice is perfect, I'm betting the first time you cooked it it wasn't. You probably had to try a lot of times to make perfect rice. Was the rice defective when it wasn't perfect? Nope. The cook got better at making perfect rice.
People should accept that no camera system is perfect. And when someone takes a crappy photo, think about what might have gone wrong and try to make the photo better the next time.
Or just keep complaining here on a user to user only forum, which Apple doesn't participate in and won't in any way make their photos better or them better photographers.
