I've just received the new Black & White Photography (issue 32), and Tim Rudman mentions that paper in his article. He used Maco's new LP Superlith to develop. He says: "Paterson's Acugrade Warmtone RC responds to extra dilution of deloper by shifting colour dramatically from cold brown to superwarm salmon orange, with intermediate colours available"
Hope Ailsa doesn't mind me 'stealing' this information from her magazine.
By the way, I find Tim's updates on lith printing very interesting! Can't wait for the next issue of B&W.
