Abstract
A cross polarization could be indispensable in certain applications when scanning and digitizing highly reflective materials or when certain applications couldn’t afford following the recommended imaging geometry 0<sup>0</sup>/45<sup>0</sup> | 45<sup>o</sup>/0<sup>o</sup> for some technical reasons. However, that puts very much color fidelity in question, to which extent a cross polarization may impact the source illuminant in the first place that is consequently impacting the color appearance during the imaging and the color correction procedures. In this research we show how certain cross polarization setups are adding a chroma tint to the light source, D50 in this study, causing by that undesirable color shift of the color of the light source. Consequently, a shift in its color correlated temperature moving, in worst case scenario, from ~5000K to ~4500K and resulting in an increased DE00 as a result of the added chroma when compared against a standard D50; nearly doubled in best case scenario and nearly tripled in worst case scenario.
