With B&W film-tests, using a good 10X magnifier, it is
easy to see the decline in resolution stop-by-stop from
f8 to smaller stops, with f16 generally being the last
"good" stop for optimum results at the image center with
35mm... (not that you cannot "stretch" to f22, but the
results are noticeably less sharp than at f8...). The
differences may be less obvious with a reduction in
resolution with copying, as with scanning...
