I am beginning to find this out the hard way.  The mathematical
relationships posted thus far do not make sense to me.  Actually,
there is a relationship between the photoshop eyedropper and
reflective densitometer output, we just do not know what it is.  All
of this is leading to Paul's practical method of using a "standard" to
calibrate the densitometer.  If anyone else has any other ideas, I
would sure be glad to hear about it.

Thanks!
