Pebbles - Material Scan

Recently I've been trying my hand at photogrammetry for my uni dissertation.
This time I wanted to try an exterior material this time around so I scanned some pebbles in the garden which was surprisingly more challenging than the brick wall I made before.
I put too much focus on capturing tons of images of the material as I was worried about having to come back outside to shoot again but after some trial and error and reducing the amount of photos I was trying to take I was able to achieve some nice results,

I rented a Canon 700D and some other equipment from my uni, batch edited all the photos in DXO PhotoLab 5, reconstructed it all with 3DF Zephyr, baked it with Designer then touched it up in Painter to achieve what you see here.
Looking forward to cranking out more these in
