Cropmarks showing enclosures, terraces, quarries. The farmer tells me that historically a couple of Roman silver hoards have come from these fields. After the grass in the field to the left has been cut for hay markings of further enclosures and pits should become more readily visible.
Just experimenting with photogrammetry of crop marks in wheat to show height difference rather than simple colour difference. I have set one of the lights as Spot and placed it at a low angle, you can rotate this light by 3-finger drag (on mobile) or ALT + Left Mouse Button. Also I suggest using the Model Inspector to look at Vertex Colour without the added light effects.
