composites in the ultra-large IMAX film format. He co-wrote (with George Turner) a book on his career and the history of visual effects, The ASC Treasury of Visual Effects published in 1983. In the 1990s, while in his 90s, Dunn joined with Japanese engineers in the development of a 3-D television system that used electronic dual-polarized glasses that auto-synched to the TV image, to create the most clear and deep 3-D images ever produced. The system was originally built for hospitals. Surgeons in many facilities are now using the system as a key aid in sorting out the nerve-endings during micro-neurosurgery. A consumer version of the system is now sold with 3-D Blu-ray players and TV sets in most video equipment stores. The system was profiled on an episode of Alan Alda's TV series Scientific American Frontiers. Always keenly interested in technology, Dunn participated in the development of digital projection for theaters.

Sawyer Award from the Academy of Motion Picture Arts and Sciences, as well as Honorary Membership in The Society of Motion Picture and Television Engineers—their highest honor. Twice elected president of the American Society of Cinematographers, he was also elected a governor of the Academy of Motion Picture Arts and Sciences in two different branches, and was instrumental in the formation of the Academy's Visual Effects branch. He also served as the AMPAS's treasurer for one several-year term.
