1.- I have been using 4x5 with with graded papers with good results for two years, and now I am interested in using VC papers. I got an old set of VC filetrs from Kodak (PolyContrast) with 7 filters labeled from 1 to 4 with 1/2's. Should I expect good results with the Ilford VC IV Fibre Paper? 2.- Using VC papers, do these papers have the same speed for every filter used?. Should I make test prints with a filter change? Or should I get the Ilford Filter Set (00 -> 5)?
