Provia 100 spectral response is more sensitive to blue light than is Velvia
100F.
Next time you get a chance, think about trying the 21 Zeiss with the 486
filter with Velvia 100F to see if there is a similar shift
to Provia 100.
Second ..... has anyone asked Schneider if the effect is caused by the
filter? They would know.
