Autumn Grass - Photogrammetry based Environment Texture

Another photogrammetry based grass material I am pretty happy with as it proves to myself that my workflow works.
To capture it I took 264 images (35mm focal length). The biggest issue I had was caused by average wind. To compensate it I picked low grass but still wasn't able to stop all leafs moving around as entire capture took me about 40 mins.
As it is part of my research I have also included slide showing difference in results between shooting with Auto White Balance and Custom White Balance setting. That difference also shows what we really see and what we think we see as our mind tricks us. As it is October in UK light is very weak, strongly influenced by clouds and surrounding environment. To capture data each shot had to be compensated by longer shutter speed. In these conditions shooting without tripod and getting sharp images wouldn't be even possible.
Custom WB should be set using 'Grey White Balance Card' to make sure result is close to real physical values.
