Just took a second look at these papers in the dark with the UV light.
William Turner has nearly the same amount of OB's as Photo Rag...these
papers really glow...in the order of EAM. I think there is a slight dulling
of effect with William Turner because of the texture...but my guess is that
it is the same coating...both containing brighteners. In contrast, Cone's
Wells River...has absolutely no brighteners...the Hahnemuhle mystery
continues....
