Default Gaining (or lossing) grades on a FB paper

Hi everybody!
Just a little question:
In your opinion,what is the tolerance of a fixed grade FB

paper?
I mean,how is it possible (having a good developing

control and using
i.e. a two bath developer) to push or pull the contrast of

a FB paper?

Thanks in advance

Lorenzo

No more than about +/- half a grade, depending on the
paper. Printing paper is developed for its maximum density.
This pretty much establishes the contrast. This is unlike
film which is only partially developed. Film is developed to
reach a given contrast rather than its maximum density, so
there is lots of range for varying the contrast. If paper is
developed for lower contrast it won't have good blacks.
However, there is still some range of variation by adjusting
exposure and development. Some developers will give slightly
lower contrast. The old Kodak Selectol Soft was good for
maybe 1/2 grade less contrst than, say, Dektol.
