A practical effect is anything captured on film which has not been achieved in post-production. In its broadest usage it can include anything an actor, makeup artist, set designer, director or other member of the production staff has managed to capture on screen during principal photography. For instance, if one wishes to depict flames, the practical way of achieving this is to start a fire and film it.
Doctor Who has historically used practical effects to a much greater degree than many science fiction shows. For instance, the backgrounds on the opening titles until the 18th season are in fact practical, because they were achieved by pointing a camera at a monitor and filming the results. Most monsters seen on the original series are also practical, because they were filmed alongside the actors in a given scene. A number of the video screens seen in the show are practical as well, in that the film on the screen was actually being played back on the screen as the actors in the foreground looked on.
Since 2005, however, Doctor Who has relied less on practical effects and more on post-production help from The Mill.
A practical effect is usually considered the antonym of a "visual effect".
