Fine grain films generally are slower speed, that is they require more
light
for exposure.
You need to look into the response curve of the film in question. If you
were to raise the volume at a linear rate and the exposure light increases
at a linear rate, the film may or may not react at a linear rate.
Different
films respond differently and the manufacturer's curves will show that.
On the other hand, human hearing response is not linear either. Just
guessing, but I suspect a linear response is not the best bet.
