I'm trying to digest a chapter in a text that cites this paper as a source. The part where it talks about what this paper addresses is pretty poorly written, so I was hoping to get the paper itself. The reference is:
S. Shafer, Using color to seperate reflection components, COLOR Res. Appl., 10, 210–218,Winter 1985.
That isn't helpful at all. I'm well aware of that site, the paper isn't on it. I'd think that's generally the first place people look when they need a paper.
