I've been experimenting with Photogrammetry with my iPhone 12 and my biggest focus has been hard surface items. I have a two point light setup, and I suspend the item using fishing line. Unfortunately, there is always a lot of noise and I can barely use the fine grained details OR capture the hard lines of hard surface.
Cameras do this stuff way, way better . Even old cheap ones. Sony A5000 for example. I also tried iphone for a while and gave up because of same reason . As of Iphone I suggest to save DNGs instead of jpgs. That way you could get true shots withoutAI improving that only makes it harder for the photogrammetry
