Ideally, you'd want to use the filter/status that most closely matches the
spectral sensitivity of your emulsion. Try the either UV setting or the
BLUE setting. If you don't have either of these settings, try getting
yourself a violet gelatine filter like a Wratten #32, #33 or #34A, tape it
in place on the densitometer and then zero the densitometer on it.
Subsequent measurements will then include this violet bias. This will only
be a stop-gap method of changing the response of the densitometer, and as
long you stick with it, it should work for you.

Which brand/model of densitometer do you have?
