Should film directors change to HD digital from celluloid?
There are pros and cons for both HD and celluloid, both with different qualities. Most directors still prefer to use celluloid as it gives the film the organic look, where as HD offers a more crisp clear look.
The pros for using HD are it can help production by

• More creativity on set and using digital visual effects and sound.
• Digital filming reduces production costs.
• Surround sound - more complex ways of recording and replicationg layers of sound.

But the downside to HD film is that it doesnt have the organic film of celluloid.

It can help distribution by

• Developing surround sound, introducing more 3d technologies and use large screens.
• There would be much faster acecss to the films as they would be downloadable directly to the cinemas rather than waiting for a real of celluloid film.
• With celluloid the quality of the film decreases over time as the film gets worn and damaged, but with HD the film will always be the highest quality.

The down side to this development is the it would be very expensive for all the cinemas to upgrade to HD screens, which would push up ticket prices and decrease the number of attendance. With this new digital distribution from the internet there is an increased risk of piracy on the availibilty of the HD digital file at the time of the box office release of a film.
