Choosing the MiniDV format
wasn't just about logistics. Its harsh imaging characteristics
corresponded well with the film's subject matter. "I saw an
artistic, logical justification for shooting this film on this
format because it was a very violent script - very disturbing,
gritty and anarchic," Dod Mantle
observes. "My main fears at the script-meetings stage concerned
where the format might and might not handle it. Those fears are
still with me as we go into release, and I see examples of [my
concerns] on the final print. I sit in the cinema and think, 'Well,
I very much would have liked to have shot that particular scene
on film as opposed to any digital format.' Projected in the cinema
correctly, the scenes in London, which are quite disturbing and
monumental, are so strong. I always fear for the variables of quality
at the release print stage. The more delicate
the negative, the greater the threat of an inaccurate density in
final print. Films of digital or electronic origin are always
more fragile in this respect. [If the release prints] are screened
at the right level and the darkness is there, even though the look
is grainy and washed out like a watercolor, a lot of people really
love it and find it acceptable."
During preproduction, Dod Mantle
performed extensive image tests in conjunction with Moving Picture
Company in Soho, London, to achieve the
best shooting combination for a filmout.
MPC believed the best results occurred with footage shot in the
4x3 aspect ratio but matted for 16x9 by the PAL XL1 (625 lines
of resolution, 900,000 effective pixels over three 1/3" CCDs)
in Frame Movie Mode, its pseudo-progressive-scan method, which
is performed electronically within the camera. "My post house
was quite adamant that it would help in their work to maintain
as much quality as possible from the original material," the
cinematographer says. "There were still all sorts of pitfalls.
Image compression can take place at one stage or another, and then
you get all of these halos and strange artifacts in the shadows.
There are certain colors, textures and lines in pictures that can
really give you nightmares when you're transferring back to film.
You have to be very wary when you're shooting. You can get surprised
in post, and then you might have to go into the Inferno or Flame
to do repair. That's less of a problem in film because of the optics
inherent to the celluloid package."
Dod Mantle helped matters by securing
the higher-resolving Canon EC (6-40mm) and Canon EJ (50-150mm)
prime lenses to the camera bodies with Optex adapters.
Even though video-lens focal lengths are measured differently than
those of 35mm lenses, traditional focus-wheel systems were mounted
onto the rods for the assistants, who pulled by eye. Because the
XL1's viewfinder is black-and-white, Dod Mantle
composed shots by looking at 9" color monitors. "It's
amazing, because this little consumer camera gets built up with
matte boxes and transmitters for sound," he says. "But
they were still streamlined and light compared to film cameras."
Dod Mantle shot as wide open as possible
with ND filters to minimize DV's seemingly
infinite depth of field, and he underexposed by one to two stops
to get more information on tape. (The XL1 has an exposure value
of about 320 ASA without altering the shutter speed.) For daylight-exterior
shots that featured prominent skies, which present difficulties
in DV, grad filters were thrown into the mix. "I used them
quite a lot because the sky burns so quickly," he recalls. "If
there's nothing there, then there is nothing you can work on digitally
- there will be a hole in the cinema screen when you go back to
print." Inevitably, the sky had to be sacrificed in certain
shots, but Dod Mantle
shot sky plates to use as replacements in post by stopping down
three to four stops and using filters to enhance the cloud formations.
In DV, backgrounds in wide shots have a tendency to become a pixellated mess,
so Dod Mantle carefully composed his shots for the cleanest
lines, taking into account the locations' architecture. "Hard
contrast lines in the background can completely take attention
away from what you want people to look at. If we do get away with
it, one of the reasons is that the film is brutal, not just [in
terms of] the violence, but also because walking out of a hospital
and finding your familiar surroundings void of people is a brutal
experience."
So is finding your parents dead in bed, as Jim does when he returns
to his family home with Selena and Mark. In a poignant sequence,
he discovers that his parents have committed suicide to avoid their
inevitable infection. Jim, Selena and Mark decide to bunk in the
house for the night, but they're attacked by a roving, red-eyed,
blood-spewing pair of infected, who are quickly dispatched. Mark
is wounded on the arm, however, and because the virus is communicable
through blood and takes hold within seconds, the ruthlessly practical
Selena quickly hacks him to pieces.
"The film has a lot of night scenes [like this], and I remember
Danny asking, 'How are you going to do this?'" Dod Mantle recounts. "I said, 'I'll just put the lights
on.' And he said, 'Well, I forgot to tell you that [because society
has fallen apart,] the electricity is all gone.' That slowly sunk
in, and after about three days I realized I was in hell."
Because London - and all of Britain, for that matter - had to
have a post-apocalyptic feel, many night sequences were photographed
using day-for-night processes to eliminate any city-light illumination.
The cinematographer explains, "You just have to put a torch
up, and you get this incredible contrast inherent to the digital
formats; they can sense light very quickly, and therefore you sense
artifice. I had to hit the actors with big HMIs shooting
through 4-by-4 and 6-by-6 silks to lift up the contrast and to
illuminate the actors' faces so you would sense that there was
some moonlight. Also, because Naomie is
dark-skinned, I flat-lit her so I could pull the shot down three
to five stops in post." Coupled with the initial one or two
stops of underexposure, the final image after post was four to
seven stops down. "Danny and I tried to push the film as dark
as we could," Dod Mantle
attests.
Three of the close-ups for the scene in Jim's home were shot through
the clear warbled window of a washing-machine lid. "I started
to develop a filter collection of all sorts of burnt and deformed
plastic," says Dod Mantle. "I
used them quite a lot throughout the course of the film to slightly
degrade the potentially brutal dimension and character of digital
imaging."
