Figure Legend:
(a) The FMS III configuration with the Wratten 47B filter and the linear polarizer. The polarizer was mounted on a ring attached to the eyepiece of the FMS III. Marks on the FMS III and a linear scale attached to the rim of the polarizer ring allowed accurate rotation of the polarizer and the same polarization angle for each subject. (b) The luminance attenuation factor as a function of the polarizer's angle. We measured the luminance attenuation factor twice to ensure reproducibility of the desired experimental luminance. The solid curve is the best-fitted sinusoidal function.
