Ah ... a spin into the twilight zone. What paper/s are you using? Ilford *suggests* (n.b. "suggests") either single or dual dichroic head settings, and they just are not the same.Originally Posted by Bruce (Camclicker)
Many moons ago I was became dissatisfied with the table giving the dichro filter settings, or more properly, the results they gave. I obtained the Ilford gelatin filter set (#0, 1/2, 1, etc.,) and with a lot of patience found that the fitration through the filters did *NOT* look much like the numbers in either table.
I plotted new curves, matching the filters ... and ... success!!!
I am convinced that there must be a LOT of variablity, enlarger-filter-set to enlager-filter set. I could give you *my* results - but I am not sure (seriously not sure) that they would fit your enlarger.
In NO case did the filtration exceed the capacity of the D5500 head ... If I remember correctly, the highest numbers I saw were in the 150's.
