RE: [Digital BW] Re: which is whiter?

Although they imply whiteness on most commercial packaging, I believe it is
a measure of "brightness" regardless of true color.  I have held some of the
papers side-by-side that have the same ISO numbers, but appear to be
different shades of white.  Some of "whiteness" will depend on the lighting
and OBAs.

I check white in pure sunlight or an Ott light. Flourescent has that green
cavity and incandescent will warm the appearance of the paper.

Not a great test, but take it to a paint department that has different
lights for looking at their paint chips.
