I am sure it is not this simple but I will ask anyways: there is a video telling you how to 3D scan for free at .5mm.
I was wondering if I got a 4K res camera would that help lower the resolution to .0x? Would a magnifying glass help lower the mm?
If not why or how could I make it work?
I would like to get it down to .01mm.
