OK, so maybe I have some major confusion about what EV means. It
seems that it does change with the ISO. I thought for a minute that
it was an absolute measure of the light levels, and that the exposure
changed with the ISO, not the EV. So, I guess we're back to the
first question: if you are testing 400 speed film, should you aim
for an EV of 4 at ISO 400?
