appearance in the manga. Motoko's demeanor lacks the comedic facial expressions and rebellious nature depicted in the manga, instead taking on a more wistful and contemplative personality. Oshii based the setting for Ghost in the Shell on Hong Kong. Oshii commented that his first thought to find an image of the future setting was an Asian city, but finding a suitable cityscape of the future would be impossible, and so chose to use the real streets of Hong Kong as his model. He also said that Hong Kong was the perfect subject and theme for the film with its countless signs and the cacophony of sounds. The film's mecha designer Takeuchi Atsushi noted that while the film does not have a chosen setting, it is obviously based on Hong Kong because the city represented the theme of the film, the old and the new which exist in a strange relationship in an age of an information deluge. Before shooting the film, the artists drew sketches that emphasized Hong Kong's chaotic, confusing and overwhelming aspects. Animation Ghost in the Shell used a novel process called "digitally generated animation" (DGA), which is a combination of cel animation, computer graphics (CG), and audio that is entered as digital data. In 1995, DGA was thought to be the future of animation, as it allowed traditional animation to be combined with computer graphics and digital cel work with visual displays. Editing was performed on an AVID system of Avid Technology, which was chosen because it was more versatile and less limiting than other methods and worked with the different types of media in a single environment. The digital cel work included both original illustrations, compositions and manipulation with traditional cel animation to create a sense of depth and evoke emotion and feelings. Utilized as background, filters like a lens effect were used to create a sense of depth and motion, by distorting the front background and making the far background out of focus throughout the shot. Ghost in the Shell used a unique lighting system in which light and darkness were integrated into the cels with attention to light and shadow sources instead of using contrast to control the light. Art director Hiromasa Ogura described this as "a very unusual lighting technique". Some special effects, like Motoko's "thermo-optical camouflage", were rendered through the use of TIMA software. The process uses a single illustration and manipulates
