For texture scan (2D), I used the scan processing in Substance Designer along with a 12×12 inch LED panel and a LED ribbon. Those allowed me to create normal maps, subsurface color textures, diffusion, and my alpha channel for foliage. The images are shot with a 5D Mark II and a 50mm f / 1.4.

I use a tripod, with my 5D connected to my computer, to import the image with EOS utility and Lightroom. I can see then the result immediately and apply the corrections in real time: Color Balance, Curve, Sharpen etc.

Seamless photogrammetry textures

Generally, for the ground textures, I shoot large areas. This allows me to bake two 4K textures from a single model generated by Agisoft. For trees, trunks, and branches, I shoot to create one texture (4K or 8K):
