4000dpi Leica scan compared to Canon capture at full res and viewed on 
a monitor. We would shoot stills for texture maps (color and texture 
for computer generated 3d sets, objects etc) or as a basis for a matte 
painting.

Digital capture ultimately won that battle for three  reasons:

a) Ultimately it was less work.

b) The suits didn't want to pay for film and processing (color C41)

c) Digital images are nearly grainless. With film I would shot 3-4 
duplicate shots on a tripod, scan them and
then average them together in to a single image. This would eliminate 
all grain, but of course my Leicas aren't
pin registered and the next frame 'drifts' a few thousands of an inch 
as you advance and no longer lines up perfectly
with the previous frame. Not the end of the world but some people 
bitched about ti. Of course that's a mute issue with digital... Every 
once and a while you will see a pin-registered F3 on ebay.

We got around the exposure range limitations of digital by making 
multiple exposures.

Gray
Gray + (x) stops (shadows)
Gray - (x) stops  (highlights)

Then a piece of software would combine the three passes and if you 
looked in the highlights you could see
the filament of a light bulb. Just like with negative film. The +/- 
value would depend on the subject matter.
We built a small robotic camera head for the camera, that would shoot 
tiles for an entire hemisphere in this
manner. You could then stitch the shots together and get a full 360 
horizontal and 180 degree vertical view.
If you saw Vanilla Sky you can see this technique in action in the 
final scene on the roof top.
I shot the tiles for that sky with my R6.2 and a 50 from the roof of 
Digital Domain in Venice, California .
Another person shot a 360 of the NY skyline from a helicopter hovering 
over New York city. The actors
and the roof were a set, located on a stage in downtown Los Angeles
