Photogrammetry works

Old photogrammetry tests.
1. The stairs were a test to see what would happen to the reflective metal rails; they disappeared.
2. Ground test of dirt and sand on a sunny day.
3. Testing types of snow. Most did surprisingly well, but some areas were so washed out with white that the program had a hard time understanding what was there, thus leaving holes in the mesh.
