Re: [ATM] How dark is dark?

[Jeff Rowe <jroweapp@swbell.net>]

Friends;
IMHO the important factor in all of this is " The angle of incidence 
equals the angle of reflection" .  Meaning gloss black when viewed 
straight on is "darker" than matt, however when viewed at an angle the 
gloss enters the picture and it is no longer the black we are viewing 
but the reflectivity of the "shine". A simple proof, take a black 
plastic garbage bag, or a piece of  thin wrinkled black plastic, and 
place it in direct sunlight. What do you see? A coal black lump, or 
regions of gray, regions of huge glare, and some regions that are indeed 
"dark"?
