I print in several of the alt processes including Pt/Pd, salt and albumen. These require very long scale negatives so my first choice is FP4+. When I am out of this I use either Efke 25 or Efke 100. Efke 25 gives me the contrast I need more readily than does the 100. I use the 100 when I need the 2 extra stops. All are developed in Pyrocat HD+.
