I've actually gotten some rather nice results from the paper.
The brownish tone you see is native to the paper, as I'm told by WW.
Haven't noted any fogging.

I realize that they're just speculations. Tried to communicate that while
also trying to describe the apparent characteristic differences. It was
not anything more than that.

It was really a comparison.
Obviously not a true scientific study, double-blind, et. al.
