The making process of these imageries are quite unique. How Unique?
These highlight objects that appealing to my eye when I walk around. I then scan them using LiDAR and make 3D objects out of it. The software creates texture files which I use algorithm to process to be duo-toned. Finally, I re-wrap them to the mesh. Taadaaa, that's how these imageries are made!

I LiDAR' ed a house I came across in my neighborhood. Then I applied duo-tone to the uv texture map using the jquery library (https://fabricelejeune.github.io/jquery-duotone/) AAAANNNNDDD this is a product of that.

The same technique was used for this. Except the object was a segment of cliffs scanned in Karuizawa JPN.
