If you want art, go get a real camera, a tripod, and study how to frame the subjects of your photo shoot.
Same applies to photos from an iPhone! If someone wants great photos from an iPhone, they should learn about composition, exposure, lighting, where to stand relative to subjects, etc.
End of the day a picture from a phone camera is better than no photo at all
True, tautologically so! It's a shopworn meme, however, and it doesn’t make the photos art. Nor does it make them good. There's also an exception — people can be so busy with their phones that they don’t live in the moment! We laugh when we see people at golf tournaments holding up their phones when they are standing at a great distance from the golfers — and watching everything through their phone's screen, just to capture photos with tiny distant golfers in them So, sometimes, having no phone or photo, just one's real life experiences and memories, can be better, much better!
Plus, whether the photo is memorable, high quality, or art, depends upon the photographer's skill
and the subject as well.
Let's see any iPhone capture a decent photo of a bird's feathers and eyes from 60’ away that is sitting high up in a tree. Or, a fox creeping through a distant underbrush. For that, a “real” camera, with a good zoom (say 20x), and a tripod will serve the photographer much better!
