Scientists and Engineers Get the Oscar for Improving Film Production and Preservation
February 7, 2007--Each year, the Academy of Motion Picture Arts and Sciences awards its
Scientific and Technical Achievement awards to the scientists and engineers that have designed
and developed technologies that contribute to the progress of the film industry.
These
technical innovations have been successfully used in movies and have become the gold standard
by which new technologies are judged. This year's 15 awards include praise for film production
and preservation. The awards will be presented on Saturday February 10, 2007.
Here is a sampling of some of this year's winners.
FILM PRODUCTION
ILM IMAGE-BASED MODEL SYSTEM

Lemony Snicket: The baby in this picture wouldn't sit still for
the filming, so Oscar-winning engineers digitally added the image later. |
Steve Sullivan, the Director of Research and Development at Industrial Light and Magic (ILM),
worked with a team of electrical and computer engineers to design and develop the ILM
Image-based Model System.
This system starts with one or more images of an object or scene,
such as a landscape, prop, or humane face. Then, a combination of computer algorithms and
artist tools are applied to create a 3D model. "The resulting model is often comparable to
a laser scan of the object," said Sullivan. "The system can help visual effects artists
create detailed models directly from a few photographs, even for subjects such as babies or
large-scale landscapes which are impossible to scan using traditional techniques."
The software behind the making of this creepy face (left) from Pirates of the Caribbean
will be awarded an Oscar this year.
To see this technology at work, check out "Wyvern" in Pirates of the Caribbean: Dead Man's
Chest or "Sunny" in Lemony Snicket's A Series of Unfortunate Events.
OPENEXR SOFTWARE SYSTEM
Florian Kainz, the computer graphics principal engineer with the Research and Development
group at ILM, designed and engineered the Open EXR software system. OpenEXR is a set of
software libraries and a file format for storing digital images with very high fidelity,
which is required for creating visual effects in movies as well as scientific visualizations.
One feature of this system is the ability to store more than just the color information
with each pixel. "For example, in computer graphics, when you want to simulate motion
blur that results from photographic moving objects," said Kainz, "You need to know how fast
and in which direction the objects in an image are meant to move."
OpenEXR's wide dynamic
range allows it to store pictures with extremely high contrast, for example, backlit
scenes that contain dark shadows while directly showing the sun. With color resolution
finer than the human eye, subtle light changes in scenes won't be lost. This system can
also let artists play with light in a scene. For example, in a picture of a room illuminated
by a window and a desk lamp, each light source to each pixel can be stored separately.
The images could then be adjusted to be a nighttime scene with the window dark and the
desk lamp bright, a daytime scene with the window bright and the desk lamp off or anything
in between.
To see this technology at work check out Pirates of the Caribbean: Dead Man's Chest or
Star Wars: Episode III: Revenge of the Sith.

FI+Z: A new wireless movie camera system takes the Tech Oscar
|
Howard Preston, President of Preston Cinema, using his experimental and theoretical
physics background has designed the Preston Cinema Systems FI+Z wireless remote system.
Up until the early 1990s, wireless devices used to remotely control camera and lenses
were unpredictable on a movie set because they interfered with the many communication devices
such as high-powered walkie-talkies commonly found on movie sets.
"The FI+Z system was the first system to utilize spread-spectrum transmission technology
which provided a reliable data link with greatly enhanced resistance to interference and
data corruption," said Preston. "The system also provided 16 bits of resolution, which
is approximately 256 times higher than the standard at the time. Over the years, the
system has gained a reputation for being reliable, precise, flexible, and rugged.
FILM PRESERVATION AND ARCHIVING
E-FILM
Bill Feightner, the Executive Vice President and Chief Technology Officer at E-Film,
designed and developed the E-Film process. When preserving film, the colors of the
film would break down over time. This made trying to keep a film perfectly intact very
difficult. With E-Film, each negative is separated digitally into 4 different negatives:
one that is in black and white, yellow, cyan (blue), and magenta (red).
Using E-Film,
these digital negatives and additional information about the colored digital negatives
could be recombined at a later date to produce the same vibrant colors they had during
the very first time the movie played. "For example, it's like taking a 35 millimeter photo and
the photo processor makes a digital image, but give the customer back a photo print,
"said Feightner, "That is essentially what we do with film. We take the film,
digitize it and put it back on film."
ROSETTA PROCESS
Phil Feiner, Jim Houston, Denis Leconte, and Chris Bushman of Pacific Title and Art Studio,
designed and developed the Rosetta process to create film master positives, which is an
exact color copy of the film for archiving from the original digital master files.
This process is unique because the digital YCM (yellow, cyan, and magenta) positives are
created directly from the film and not from a digital version.
"The Rosetta Process starts
with laser recording of the film to create the YCM positives," said Feiner, President of
Pacific Tile and Art Studio, "Then, a reverse-color negative of the film is produced,
which means that anything red in the image would look green on the negative. A print from
this negative is compared to the original print.
The black-and-white separations from this
process have a potential shelf life of more than 1,500 years when properly stored.
"It uses digital film recording to archive motion pictures for easy restoration to
the original appearance of the film in theaters regardless of how long the film elements have
sat on a shelf," said Houston.
