Scott Farrar, a graduate of UCLA film school and graduate school, is a Visual Effects Supervisor at Industrial Light & Magic (ILM), a position he held when he worked on the effects for Star Trek VI: The Undiscovered Country. His first contribution to the Star Trek franchise, however, was as photographic effects cameraman on Star Trek: The Motion Picture in the employ of Douglas Trumbull's Future General Corporation, after leaving Robert Abel & Associates when that company was pulled from the project.  In 1980 he joined ILM by a lucky happenstance when he was called by a friend who worked at that company, "They needed a union cameraman. They were starting to get more shows in and wanted someone who knew visual effects but who could also shoot plates on set."  Hired for seven months he never left. The project he was called in to help was Star Trek II: The Wrath of Khan. During his early years with ILM, he also worked as special effects cameraman on Star Trek III: The Search for Spock.
Joining ILM as a visual effects cameraman, Farrar's early work includes Star Wars: Episode VI - Return of the Jedi, Willow, and Who Framed Roger Rabbit. His camera work on the film Cocoon helped ILM win an Academy Award for Best Visual Effects in 1986. After becoming an ILM Visual Effects Supervisor in 1988, Farrar helped the company earn three more Academy Award nominations for their visual effects work in the films Backdraft, A.I. Artificial Intelligence, and The Chronicles of Narnia: The Lion, the Witch and the Wardrobe. His other credits as an ILM Visual Effects Supervisor include Cocoon: The Return, Back to the Future Part II, Back to the Future Part III, Wolf, Amistad, Deep Impact, The Mummy, Star Wars: Episode I - The Phantom Menace, Minority Report, and, most recently, 2007's Transformers (written by Roberto Orci and Alex Kurtzman). He was also an additional effects plate photographer on Jurassic Park and supervised the visual effects of the end sequence in Men in Black.
Scott's daughter, Katherine, is a visual effects coordinator at ILM. According to the Internet Movie Database, she has worked on the new Star Trek film, simply titled Star Trek, as visual effects associate production manager.
