Digital BW, The Print

Well Portfolo Rag is a very nice paper. I just saw where William Christenbery has produced a lot of his old famous work with K3 on it. 
One 8x10 of one of his most popular images is selling for $20 grand each.

But Port Rag is never going to achieve the universal results of Photorag because it is too warm. I just had a painter tell me to please not use it again because it is "dull" in comparison to PRag.

Look if there is a coating issue with Photorag I'll bet anything the same issue will be attached to William Turner, Museum and German Etching, etc. I bet it is the same coating on all,or very similar.

The one thing that made me  rest a little about Photorag was the >240 year for color rating the Wilhelm gave the HP version with Vivera inks. But I don't trust even that test anymore.
