I should warn you that the Multigrade Fiber Base (not Warmtone) Matte is very, very matte... it's matte to the point where I had difficulty telling which side was the emulsion! In case you don't know, with FB the paper will always (AFAIK) curl towards the emulsion wide. I wish I knew that when I used this paper!
Yep. Tell me about it. I wasted three whole sheets and a litre of good developer before I could figure it out what was going on. But hey, it's a wonderful paper, although I remember it being a whole lot less white when I last used it.
