PBR – shooting and calibrating base colour textures

Martin Geupel has published a new article in which he critiques some of the common practices used to determine base colours in Physically Based Rendering. Geupel asserts that PBR validators fail to account for specular reflection when determining basecolor, leading to skewed representations of materials, particularly darker ones. He argues for a more nuanced approach, suggesting that proper calibration often leads to basecolors appearing darker and more saturated than anticipated. This development may prompt a reassessment of PBR practices and improvements in how we take a proper measurement of just the diffuse reflection of a surface. Read more on the Racoon Artworks website.
