Photogrammetry - Creating Roughness Maps

In this short video I show my current process on how I create my roughness maps using a very basic Cross Polarization setup. Cross Polarization Setup: Void Scanning method: Turntable Setup: Main gear used in this video: - Sony A7RII with Canon 50mm 1.8 - F&V R-300 - Circular Polarising Filter - Linear Polarization Sheet - Manual Turntable - Reflector (Black side)
