Excerpt from "Love and War" by Judy Duncan, Cinefex #90:
"...The sail ship lands in a small hangar, the interior of which was built as a miniature in the final days of production. Exteriors were 3D matte paintings. After a brief meeting between Dooku and Darth Sidious, the movie cuts to the interior of the Jedi temple, where a somber Yoda, Obi-Wan and Mace Windu consider the impact of the impending war. Yusei Uesugi provided the dramatic sunset view outside the temple windows, augmenting a photographic element with matte painting. "I knew, from thirteen years of being a matte painter, that it is impossible to paint a sunset like this," Uesugi said, "and that photographing a real dramatic, beautiful sunset was going to be essential. So for almost half a year, Masahiko Tani and I went outside every evening, looking for that gorgeous sunset to photograph. By the time we had to start working on these shots, we had taken about three hundred pictures; but none of them were very good, and I was starting to get nervous."
About that time, Uesugi took his vacation, visiting a friend in Tokyo. Coincidentally, his friend had taken a number of digital phtographs of a very dramatic sunset. "It was the sky on September 11 that he had photographed," Uesugi said. "The skies were so dramatic, he had thought to himself that it looked like the end of the world. Then, few hours later, he found out what was going on in New York. He was kind enough to let us use those digital images for these shots."..."
