full-dome video thoughts vs. film thoughts
- Hi all,
I have faith that video will *someday* truly advance to the quality we currently
find with film. What I wonder about, however, is the cost of production for the
two. I don't have the information at my fingertips, but I have seen numbers for
how much it costs per minute to produce a large-format film. While I am certain
that producing video for full-dome is not cheap, I wonder how it compares with
the cost of making a comparable piece of film. Anyone?
Is producing for full-dome video less cost prohibitive than producing for film?
If so, I should think that the resulting versatility would tip the scales in favor
of video in most instances.

Motion pictures require a 'shooting ratio' of as much as ten to one to
end up with a selection of suitable material. Sheer media cost is the
reason most imax films are dull travelogues trying to 'wow' you with high
res helicopter moves.
Some day a specialized digital high res recording device capable of
capturing 30 frames per second color images for dome use will appear. Until
then film is the best means of bringing the real world into the dome. Film
is, as I have stated, still king of the image gathering hill. Material shot
on film and transferred to video always looks better than similar material
shot on video. So long as this is true film deserves to survive.
Making a 3D digital enviornment and animating within it is in a way a
more self contained method, requiring no hauling of heavy equipment,
building and lighting of model sets, or large studio space. If a different
variation of a sequence is needed a new one can be rendered with few
physical resources being used. Once within this operating enviornment, the
operating costs are far less than a similar project done on film.
At the moment the bridging of the gap between film and digital methods is
terribly expensive, be it by transferring digital images to 70mm film or by
scanning the film negs into high res animation files. Many large format
film sequences deserve to survive in digital media.
