Right, so to compare *films*, one needs to use identical situations for
each film.

On the other hand, once one has selected a film, and wants to be able to
expose and print "by the numbers" ala BTZS, you might run in camera
curves for each lens under low, medium and high flare situations.

At some point, this gets a bit ridiculous, as you can spend more time
testing and calibrating than taking actual pictures and making real
prints.... it is at this time that development by inspection starts to
look very attractive :-))
