Historically, I ‘ve used a number of black and white films, including Ilford FP4 and Ilford Delta 100. Recently I have been using mostly Ilford’s XP2Super chromogenic film.
I use exclusively Ilford’s Multigrade IV RC printing paper – it’s reliable, consistent and I know how it behaves! (I do have some more interesting papers in the fridge, but somehow I never get around to trying them!).
For producing sepia prints, I recommend Tetenal’s Triponal Toner – it gives good, consistent results, is pleasant to use, and has a high capacity. I now make up the equivalent from raw chemicals, as this is more ecological (fewer plastic bottles!!) and economical.
