Re: testing 320 and 400 speed film using plotter software

Nope, if you are using your Gossen Digisix, set the meter to ISO100, and
expose for EV2 at 2/5 of a second. My previous lengthy email explains the
funky nature of the digisix.... And this will ensure that your 2.4 speed
point that the plotter assumes will be correct!
