Although Star Wars had revolutionized the use of computerized motion control miniature effects, The Black Hole was shot using a blend of traditional camera techniques and newly developed computer-controlled camera technology. Disney wanted to rent equipment from Industrial Light and Magic, but it was unavailable during the film's production period and was prohibitively expensive. In the end, Disney turned to its own engineering department, which created the A. C. E. S. (Automated Camera Effects System). The computerized system allowed for the camera to take double exposure photographs of the miniature models as it moves convincingly across the matte painting. It also permitted the actors to move unrestrictedly within a matte painting, and the camera tracks them within a non-existent set that would be painted in later. The Mattescan system was then used to composite live-action shots onto a single matte painting while the camera is in motion on several axes. In total, 150 matte paintings were created for the film under the supervision of Harrison Ellenshaw, but only 13 were used in the film.
