I've used many (and I mean many) combinations of paper and developer over the years, but I think I've found the best yet for me. I'm currently trying Ilford Warmtone FB in their warmtone dev. I've used their wartone FB for some years, but have never got the warmth people keep banging on about. But this 'new' dev. is brilliant. I'm getting warm tones like I used to see in Agfa Record Rapid (anyone remember that!), well perhaps not that warm, but you get the idea. And it lasts. I used it over a three day printing session and, despite it turning the colour of strong pee, it remained active. I wonder what it'd be like with Forte Polywarm FB. Any one tried it?
