Thanks for the reply, BMbikerider. My DUKA is much closer to the enlarger than yours which I admit I hadn't taken account of but when I get new paper I must try it on a higher setting as I might get away with as much as 10-12 which is a third of the way along the light intensity setting. I do so hate being in the dark, literally and metaphorically
I think the Kodak units cover an even greater range than the Durst 0-130 so you'd think that the equivalent Durst settings would be even lower than your Kodak ones on the LPL?
A puzzle but I can only do a fresh trial if and when I get FUJI CA paper.
