I have my own Photogrammetry process for 3d scanning. this allows me to create completely accurate photorealistic models of any item I have access to very quickly using nothing more than a camera and light setup and my software. I have a baking and optimising process that allows me to extract low poly extremely efficient models from my scans with perfect quads only topology so the results can run in any format required from games to high end animations this is one effective way to get absolute realism into your projects
