Warner Bros. widescreen format with anamorphic-like character — classic cinema format with warm optics and distinctive lens flare. Less common than CinemaScope.
In the 1950s, Warner Bros. attempted to establish its own widescreen format with WarnerScope — an anamorphic solution intended to compete with the dominant CinemaScope. The optical characteristics differed subtly: while CinemaScope utilized Bausch & Lomb optics, WarnerScope employed specially calibrated anamorphic lenses that produced a warmer overall impression. This had consequences for lighting and color temperature — the lenses absorbed noticeably more red tones, leading to a golden, slightly desaturated look in daylight shots.
Practically on set, you notice the difference immediately: WarnerScope is more prone to flaring than comparable CinemaScope lenses. Backlight and incidental light produce those characteristic bokeh bars and ghost images typical of anamorphic lenses more quickly — some DPs consciously use this for atmosphere, while others fight against it. The focal length equivalents are similar to CinemaScope (2:1 squeeze ratio), but the depth-of-field characteristics feel slightly less controllable. The bokeh is softer, more diffuse — less elegant than Panavision, less crisp than classic Technovision lenses.
The format never truly caught on — by the early 1960s, WarnerScope had practically disappeared from the market. The reason: studio competition was brutal, and Warner Bros. could not enforce its standard against the established CinemaScope infrastructure. Cinemas already had anamorphic projectors for CinemaScope; installing an additional format was an effort without added value. Today, you primarily find WarnerScope material in restored classics from the late 1950s — and even there, it was often rescanned or even refilmed for re-release.
For contemporary productions, WarnerScope is irrelevant. However, it is archaeologically interesting: it shows how studios wanted to use technical standards as branding tools. The lenses themselves are considered underestimated by enthusiasts — warmer, softer, less clinical than modern anamorphic. Those who specifically want to shoot in this archival look can find the lenses today only from specialized vintage rental houses, and usually in questionable optical condition.
