Have you looked at the comparison of how a camera follows a matrix profile
depending on the light spectrum?
From one of my previous,
" A ColorChecker SG card, shot with D4 under halogen lights, first time no
filter on lens, second time with B&W KB15 (80A) color conversion filter on the
lens. Matrix profiles were calculated from both shots, for delta E 2000 reports
see .csv files in http://cl.ly/3x3F0D2p0e3K/D4_16-35_SG_Halogen_dE2000.zip";
