6.6.2.4 Solution: Correct One or Both Eyes
The problem here is not the highlight itself, but the difference with which
the highlight appears in each eye. If the team determines that the highlight
mismatch needs to be resolved, the team can either duplicate and track a
similar highlight in the other eye or paint out the highlight entirely in the
visual effects workl ow or using a secondary color grading.
6.6.2.5 Issue: Polarization Mismatch
Polarization mismatches appear as differences in the amount and quality
of light rel ecting as highlights or as glare from rel ective or semi-rel ective
surfaces in a scene. Typically this happens with glass and other shiny or
polished materials. Polarization mismatches occur in both parallel and
converged imaging systems when L or R “see” rel ections at a slightly
different angles. What the imaging systems see is what you process in post.
These mismatches can grow more problematic the larger the rel ective surface
and the longer the viewer sees the rel ective surface. Some production tools
exaggerated for clarity
L or R show different white values
for some reflective objects
