Except that the moon is about as dark as charcoal.  We don't usually
notice, since we always see the moon against a darker background,
making it look bright.

It is significantly brighter when it's full than when it's almost
full, however, due to shadowing effects.  The same is true on Earth,
but it's usually hard to notice the bright anti-solar point since your
head (or camera) gets in the way.  You can sometimes see it from an
airplane.

Of course you need a longer exposure during totality.
