Visual effects designer

s were the people in charge of what was called "visual effects" during the 1963 run of Doctor Who. Their title is only historically accurate, however, due to the fact that the film industry has since differentiated between "visual effects" and "special effects". Most of what Doctor Who "visual effects designers" did would now be considered "special effects" by BBC Wales, because most of it happened in-camera during principal photography, rather than during post-production.

A variety of credits
This position was credited in several different ways. Because of the widespread interchangeability of the terms "special effects" and "visual effects", the job sometimes was credited with "Special Effects Designed by" on the occasional serial, going back as far as The Wheel in Space. The position was also credited as simply "Visual Effects" on a few serials, dating to The Tomb of the Cybermen. However, with the Barry Letts producership, the majority of serials bore the credit, "Visual Effects Designer". Still, the position was in flux, with some serials bearing both "Visual Effects" and "Visual Effects Designer", and one serial having the credit "Visual Effects Design".

Beginning with Tom Baker's first story, the name of the position was finally standardised as "Visual Effects Designer", and it was never changed again throughout the remainder of the original run of the programme.
