Mar 19, 2003/ FW/ --- The Oscars are upon us and -- once again -- the spotlight is being focused on stars like Jack, Nicole and Renee.

But what about Dion, Pawel or Conrad? If those names don't sound quite as familiar to you, it's probably because you'll never see them in front of the camera.

But their work is nominated for Best Cinematography. And while everyone knows what it takes to get a best acting nod, not many people are familiar with what cinematography is -- even though it's one of the most important awards given on Oscar night.

Directors depend on cinematographers to turn their vision into reality. While the director is responsible for running the show -- from actors, to writers to costumes to sets -- it's often the cinematographer, behind the camera, who brings the script to life.

Cinematographers are also often referred to as DP's -- or Directors of Production -- and it's their expertise that makes a romantic scene look soft or a rainy night look ominous.

They choose what kind of film and lighting will capture the mood of a scene. The films up for the cinematography category -- CHICAGO, GANGS OF NEW YORK, ROAD TO PERDITION, THE PIANIST and FAR FROM HEAVEN -- are being honored for the vibrant and emotional way these movies look.

Even in this so-called digital age, film is still the medium of choice for the most acclaimed cinematographers.

Most cinematographers feel that film gives a softness and warmth to a picture that cannot be captured digitally. It's no surprise that every best picture winner has been made on Kodak film.

The 75th annual Academy Awards air on March 23rd.

Nominations for Best Cinematography are:
Dion Beebe -- CHICAGO
Edward Lachman -- FAR FROM HEAVEN
Michael Ballhaus -- GANGS OF NEW YORK
Pawel Edelman -- THE PIANIST
Conrad L. Hall -- ROAD TO PERDITION
