This is what got me started but my process is somewhat modified and customized to my liking. I use Reality Capture for the 1st step and I typically reduce geometry to 15k triangles. I do not have a DSLR so I just use my phone with a turntable and a lightbox. I still use Blender for editing and finalize the output with Unity. Be sure to make your collider convex in Unity.

thanks for the infos.... I hope I have the patience to go through all that
