Actually, whilst we are on the topic of Paterson, is anyone looking forward to FX-50 coming back?
After the fanfare of its launch and some amazing reviews including an excellant one by Roger Hicks (you can get the pdf of this from the Paterson website) it seems that FX-50 never achieved the popularity that might have been expected.
I know there were lots of reported problems with one of the liquids going off very fast. This has always made me cautious to use it. I bought a small box of it 2 years back but never got round to trying it - out of fear I suppose. What caught my eye was the references to FX-50 having the tonality of Aculux2 with all the speed advantages of vit C and modern developers plus good sharpness.
