Sean, I agree it does make the slide thinner, and I agree it does reduce the
dynamic range, but how does that reduce the sensitivity of the slide film to
faint light?.. the hypered pj400 literally captured more of the neutral colored
portions of the galaxy..

Note how even pushed +3, E200 still has less grain than PJ400?
