Photogrammetry

I have been experimenting with photogrammetry. This is a rock small enough to fit in the palm, but with the right kind of setup, it can hold much detail. This is the beginning of a piece that uses macro photography as the basis of making large scale scenes. With travel limited these days, on location photogrammetry maybe limited for many. 
Pertinent Information:
Camera: Sony a7r3 - Tamron 28mm-75mm at f18 - ISO 100 - 3.5sec exposure time - A total of about 340 images at 42 megapixels.
Software: Agisoft Metashape Standard, ZBrush, Marmoset
Original Mesh Poly Count: 14.5million
ZBrush ZRemesh to 14K
I plan on making tutorials to explain the process comprehensively.
