Career outside Star Trek
Starting his career in 1927 as second cameraman on Hawk of the Hills (1927), and having worked on one of the very last silent serials, Queen of the Northwoods (1929), Linwood Dunn, outside of Star Trek, shot VFX for a number of acclaimed, classic feature films, including the original 1933 version of King Kong, Orson Welles' 1941 drama Citizen Kane on which Robert Wise worked as editor and on which Dunn also served as an instructor to Wells on the use of the optical printer, the Wise co-directed musical West Side Story (1961, starring Richard Beymer), and Stanley Kubrick's 2001: A Space Odyssey (1968, which starred Gary Lockwood and featured Ed Bishop). Dunn received an Academy Award nomination for his work on the 1966 film Hawaii (featuring Lou Antonio and Torin Thatcher, and Gil Perkins as stunt coordinator).

Apart from being a cinematographer, Dunn was also throughout his career, an active inventor and developer of cinematographic technologies for practical use in the motion picture industry, such as one of the first zoom lenses. Especially noteworthy in that respect was the work he did on the development of the . While not invented by him, his work made it a practical piece of equipment for use in the production of motion pictures, especially crucial where the production of VFX was concerned. In that role, he was the recipient of two special Academy Awards for the development of the Acme-Dunn Optical Printer: the 1945 Technical Achievement Award and the 1981 Academy Award of Merit. The  also awarded Dunn with a Medal of Commendation in 1979 and the Gordon E. Sawyer Award in 1985. 

A pioneering innovator in the field of visual effects, Dunn's talents became a much sought after commodity by other production companies, so much so in fact, that he decided to go into business for himself by forming his own effects house, Film Effects of Hollywood, in 1946 (though, at the time, he initially kept his job at RKO Pictures as well).

In addition to Citizen Kane, Dunn worked on hundreds of other films for RKO Pictures, including the 1942 horror picture Cat People, the 1947 film noir Out of the Past (which featured Richard Webb), the original Mighty Joe Young (featuring William Schallert), the cult 1951 science fiction thriller The Thing from Another World (which starred Kenneth Tobey), and the infamous 1956 John Wayne adventure The Conquerer (which featured John Hoyt and cinematography by William E. Snyder). He was also the one who photographed the rotating radio tower used in RKO's famous logo. 

Other films on which he provided photographic effects include the 1963 comedy It's a Mad Mad Mad Mad World and the 1970 thriller Airport (featuring Michael Bell and Vic Perrin). He did VFX on a 1975 horror film The Devil's Rain, in which Star Trek star William Shatner has a supporting role. The film also features George Sawaya. He was subsequently elected president of the prestigious American Society of Cinematographers (ASC), into which he was already inducted in 1950, twice. He was also elected 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. Later in his VFX career, he specialized in doing opticals in large film formats such as 70mm, Imax, and World's Fair multi-image exhibits.

Linwood Dunn sold his VFX company in 1985 to  and retired from active effects work, but remained active as a consultant and inventor. His last invention was a prototype for the Hi-Def 3-D video projection systems now widely used in many movie theaters, on which he was still working when he died in Los Angeles, California, in 1998 at the age of 93.
