Sen Wood Quarter Cut - Photometric Stereo based PBR Veneer Material

A 10 by 10 cm material of sen wood (quater cut: Japan). Captured with Photometric Stereo technique the way I described in one of my recent videos already (based on 16 images):

I used AD200 Pro flash with TTL setting as a source of light since I proceeded with the capture in a daylight.
This time for photometric stereo reconstruction I used Details Capture. Color was tweaked to match color spectrometer measured values. For those interested I shared more info in this video:

These certain values with 49 other verneers color measurements were added to the paid version of this list:

At some point when the list is large enough and I manage to cover metals finaly, I plan to share it in form of a new color reference video, so big thanks to those who purchased it as it helps me to co-fund my current research a lot.
Cheers!
