It's not clear to me that this is the case. Consider the following
experiment:
Suppose you have a big, bright lamp and some ideal, black cardboard that
doesn't let any light through.
In scenario 1 you cover the entire lamp with cardboard except it has an
an 'A' shaped hole cut in it. Since the cardboard is ideal, we get a
glowing A on a black background.
In scenario 2, you hang an 'A' shaped mask in front of the lamp so that
you get a black A on a bright background.
Will the two As appear to have the same weight? I'm guessing the glowing
one will appear bolder than the dark one.
