Terry,
Good, since you have a Stouffer step wedge just go ahead and do the
test I suggested and report your readings of each step from 1-21.
Just make sure that Step 1 is at paper base white.
If you do that, and still don't understand the implication of the
results for digital negatives I will just have to leave you on your
own.
