Sand - Photogrammetry based Environment Texture
Sand - material I captured to create my recent video tutorial. Video can be found on my youtube channel for free:

This is my photogrammetry workflow - still experimenting with 'Artomatix' and replaced Photoscan with Metashape (more details regarding to my workflow at: https://www.artstation.com/artwork/K0PYG)
The source - weather conditions during the capture and the way I used light reflector. I made a mistake and I should face white side instead of golden one towards the surface I was trying to capture
Magic - conjuring the light reflector ;P
The Source - captured area
The source - surface details with my shoe, ruler and color checker as scale reference
The source - the surface after the capture was over :)
The reference image with the Color Checker included - used to calibrate color and tweak white balance in PhotoLab2
Metashape - surface reconstruction based on 137 images
ZBrush - builiding lowpoly model for baking. Captured ruler is very useful as scale reference and helps to define lowpoly-model size. In this case I wanted to cover 180cm x 180cm of real space.
Artomatix - graph I used to remove seams and fix all glitches. In 2D view Ignore-mask preview as info for AI based reconstruction and seam removal
