Digital Cinema comming of age.
The Sony CineAlta™ 24p HDW-F900 HDCAM™camcorder system that was used to shoot Star Wars Episode 2.
Sony and Panavision worked with Industrial Light & Magic (ILM) and Lucasfilm on a series of tests that convinced George Lucas and producer, Rick McCallum of the benefits of shooting in digital 24P at 1920 x 1080 HD sampling.

The cost savings for Film Makers is tremendous. Said the producer McCallum, He estimates a saving of US$1.6 million in film stock, dailies (rushes), sound transfers, lab and telecine costs alone. He also maintains that he can document a total saving to the overall production of between $2.5 to 3 million dollars, by shooting HD over film.

On Star Wars Episode 1, Phantom Menace, Lucas shot the equivalent of 1.2 million feet of 35mm film (or about 20,000 feet a day). This would have cost the production $684,000 just for the raw film stock alone. By comparison, Lucas only spent $15,000 for HD tape stock.
For Episode 1 they scanned over a million feet of 35mm film into the digital domain, so they could input it to their computers, making Episode 2,this step was skipped saving some $500,000.
During the shooting, they made true video clones of all the material each day. So they could produce a number of masters that were effectively indistinguishable from each other. This procedure dramatically reduced their negative insurance costs to the tune of about $125,000.

Additional information can be found in the article "Digital Cinema By George" published in the American Cinematographer magazine, September, 2001 page 66. Also in the article "Framing The Future" on page 76 in the same issue.
Filmmaker George Lucas has authored technological innovations feb18 2004, The HollyWood Reporter

Lucasfilm is now using Sony's New 4:4:4 High-Definition Recording System For Star Wars: Episode III, HDC-F950 HD camera and the SRW-5000 HDCAM SR VTR. The HDC-F950 captures uncompressed images at a resolution of 1920 x 1080 in 4:4:4 RGB

Plus8Digital, the digital motion picture technology rental company with offices in Burbank, Calif., Vancouver and New York City, will supply the HDC-F950 camera and HDCAM SR equipment to Lucasfilm.
The HDC-F950 HD is a more advanced version of the HDW-F900 A significant system innovation is facilitated by a 3Gbps fiber optic link from the HDC-F950 camera head to the new HDCU-F950 camera control unit using the SMPTE 304M & SMPTE292M standardized composite fiber/copper cable system.

Sony Projector Gets Bright Images From Black Screen
The New York Times reported - Sony has developed a new projector that can give a bright, unfaded picture without the need to eliminate ambient light. The secret is that they project onto a black screen instead of a white one. Their screen uses species filters so that white ambient light is absorbed, but the red, green, and blue light from the projector is reflected. Sony sees a possible use in home entertainment systems because of the ability to have a much bigger picture than conventional TVs as well as businesses adopting the projectors for presentations.

Conventional Screens
Reflect all light, including a room's ambient light, making for a faded picture in a well-lit room

Sony's high-contrast screen

Other BlackScreen Technologies

At Projector Summit June 7&8 2004
Salvatore Suniga, President of Jenmar Visual Systems (The leader in Blackscreen technology) also spoke about their BlackScreen for rear projection applications in video wall, avionics and advertising. It has now developed a BlackScreen product for Rear Projection TV with some unique features. The presentation will focus on these unique features, when is the product going to be available, and its price points. The Jenmar BlackScreen RPTV product will allow producing RPTVs OEMs to complete directly with LCD and Plasma display products with similar performance characteristics as well as improving others. The BlackScreen RPTV will have similar viewing characteristics as LCD and Plasma displays, but much better resolution, contrast and ambient light control.

Synelec Telecom Multimedia of France also make the LM 800 and LM 1000 black screen Rear-projection DLP Cubes

Lusoscreen from Portugal, can project images outdoors during daytime brightness levels.
