High-key lighting is a style oflighting forfilm,television, orphotography that aims to reduce thelighting ratio present in the scene. This was originally done partly for technological reasons, since early film and television did not deal well with highcontrast ratios, but now is used to suggest an upbeat mood. It is often used in works ofcomedy. High-key lighting is usually quite homogeneous and free from dark shadows. The terminology comes from the higher balance in the ratio between thekey light and thefill light in a traditionalthree-point lighting setup.[1]
In the 1950s and 1960s, high-key lighting was achieved through multiple light sources lighting a scene—usually using three fixtures per person (left, right, and central)—which resulted in a uniform lighting pattern with very littlemodeling. Nowadays, multiple hot light sources are replaced with much more efficientfluorescent orLEDsoft lights, which provide a similar effect.
The advantage to high-key lighting is that it doesn't require adjustment for each scene which allows the production to complete the shooting in hours instead of days. The primary drawback is that high-key lighting fails to add meaning or drama by lighting certain parts more prominently than others.
Shows with bigger budgets have moved away from high-key lighting by using lighting set-ups different from the three-point standard. Part of the reason for this is the advent of new lighting fixtures that are easier to use and quicker to set up. Another reason is the growing sophistication of the audience for TV programs and the need to differentiate.
High-key lighting found its use in classicalHollywood cinema because it was well suited for three-point lighting and other filmmaking traditions.It is an overall lighting design which uses the fill light and backlight to create low contrast between brighter and darker areas. It can be used for both daylight and night scenes.[2]
