Characteristic horizontal blue light streaks produced by cylindrical front elements of anamorphic lenses when light strikes the optical axis at 15–45° incidence angles.
Technical Details
Anamorphic flares are created by cylindrical front lenses with compression factors of 1.33x to 2x, which refract light horizontally differently than vertically. Standard anamorphic lenses like the Panavision C-Series or ARRI Master Anamorphics produce flares at angles of incidence of 15-45° to the optical axis. The characteristic blue streaks typically measure 200-800 pixels in height in a 2.39:1 Cinemascope format. Modern lenses like the ARRI Signature Primes offer controlled flare characteristics through multi-coating processes with up to 12 layers of coating.
History & Development
Henri Chrétien developed the first anamorphic system, "Hypergonar," for the French military in 1926. 20th Century Fox adapted the technology in 1952 as CinemaScope with "The Robe" as the first anamorphic feature film. The distinctive flare effects only gained conscious aesthetic significance in the 1970s through films like "American Graffiti" (1973) and "Star Wars" (1977). Cinematographer Haskell Wexler used them specifically for nostalgic moods, while Douglas Trumbull employed them for science fiction atmosphere. Today, manufacturers like Cooke offer various flare intensities with their Anamorphic/i series.
Practical Application in Film
Denis Villeneuve and Roger Deakins systematically used anamorphic flares in "Blade Runner 2049" (2017) to enhance the futuristic atmosphere, combined with practical light sources. J.J. Abrams popularized intense lens flares in "Star Trek" (2009) through targeted LED illumination of the lenses during shooting. The typical workflow requires precise light positioning with HMI or LED panels at a 30-60° angle to the lens. Disadvantages: Flares can obscure details and require additional takes without flare effects for post-production.
Comparison & Alternatives
Spherical lenses produce round, concentric flares without horizontal streaks. Digital flare simulation using software like Optical Flares achieves 80% of visual authenticity at significantly lower costs. Modern full-frame lenses like the Panavision DXL system enable anamorphic looks without traditional drawbacks. Vintage lenses like the Kowa Anamorphics from the 1960s offer more intense, unpredictable flares, while modern designs like Atlas Orion provide controllable effects.
