Ash White - Photometric Stereo based PBR Veneer Material

A 10 by 10 cm material of American White Ash (quarter cut). Captured with Photometric Stereo technique the way I described in one of my recent videos already (based on 16 images):

This time seam removal and heightmap based Ambient Occlusion was done in Substance Sampler. Despite all Sampler's problems, glitches and faky blending, feels like it does better job for this type of structural surfaces to ArtEngine.
Tp capture veneer, I took two additional images with AR400 flash light - 1 cross and one parallel polarised to capture roughness map. It was calculated by subtracting one image from another. Image misalignment caused by camera micromovement were manually corrected in Affinity Photo. Additional 16 images for Photometric Stereo reconstruction were captured with the AD 200 Pro flash in TTL mode. PBR data was generated in Details Capture.
Color was adjusted to match value measured with color spectromenter. For those interested to get list of values for different materials I shared them in this video:
