Teak QarterCut - Photometric Stereo based PBR Veneer Material

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

This time I took two additional images with AR400 flash light - 1 cross and one parallel polarised - and generated roughness map by subtracting one from another. With AD200 Pro flash in TTL mode I captured additional 16 images for Photometric Stereo reconstruction in Details Capture. Next I used an ArtEngine for seam removal and roughness subtraction. Additional tweaking and hight correction was done in Photoshop. Surprisingly generated color and luminance values were totally in matching range of values measured with color spectrometer. For those interested to get list of values for different materials I shared the in this video:

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

At some point when the list is large enough and I manage to cover metals, I plan to share them all in form of a new, free color reference video, so big thanks to those who purchased it as it helps me to co-fund my current research a lot. So far my result with metals are pretty tiricky as in my research they appear much darker to all commonly known and shared values.. so its going to take way more time before I share mine results as I want to be 100% sure they are correct.
Cheers!
