I've messed with it a bit, using color negatives shoot without filtration.
Some images gave good results, some not.

One problem is that by darkening the blue channel (I pull it way back in
channel mixer, and pump up the red channel, add a dash of green and pull
back on the constant slider) it seems to really accentuate whatever noise is
in the blue channel, which in the case of my scanner is considerable. It
also gives a strange variance in grain across the image - much more in the
sky than in the rest of the image for instance.

So, sometimes tonally you could get the effect, sometimes not, but even when
you could the grain/noise issue was weird.

Again, just my results with my equipment.
