Combining thousands of imagesfull-size and miniature to create the stunning wall-to-wall special effects for this intergalactic fantasy
t this time, the ultimate image quality, least apparent grain, highest resolution and accutance, and best tone range and color saturation are produced in first-generation, or camera-original negative. Copies or generations of film derived from an original exhibit the familiar degradation of each of these qualities. In special effect matte photography, the most difficult and rewarding results are obtained when all components in a shot are composited "in camera." This method, also called the "held take" technique, places all the difficulties of color balance, exposure, film shrinkage and matte size/fit in the hands of the miniature stage photographers. Many shots in 2001: A Space Odyssey were produced in this manner. However, in a film such as Star Wars, where the shots pose difficulties in miniature photography which have not been attempted in such quantity, the held take method would preclude a realistic production schedule. Our approach was to transfer the difficulties of composite matte photography from the miniature photographers to the optical cameramen. This achieved an effective balance between capturing the images on film, and finishing them into composites; it also gave the optical cameramen the challenge of maintaining maximum second generation quality in the optical composite negative.
A It was decided to use black and white three-color separations for all primary images in the composites. The emulsion of 5235 color separation stock has a wide contrast latitude and grain definition which is superior to 5243 color interpositive: it is the best choice for quality.
