Schneider 4 x 5.65″ 4mm Blue True-Streak Filter

The Schneider 4 x 5.65" 4mm Blue True-Streak Filter, offered by Lightbulb Rentals, is designed to enhance point light sources such as the sun, light bulbs, or candles by creating distinctive streaks. Embedded within the filter's glass are fine line patterns specifically engineered to interact with these light sources. When used, the filter produces elongated streaks reminiscent of those captured with an anamorphic lens and viewed through a complementary reverse projection lens. These streaks extend horizontally from each point light source, adding visual emphasis or creating dramatic effects within the frame. Anamorphic lenses are traditionally used to achieve a wider aspect ratio than standard spherical lenses on a 35mm format. This process compresses and distorts the image, which can be corrected by projecting the footage through a reverse anamorphic projection lens. This correction not only restores proper proportions but also generates elongated, horizontally symmetrical highlights from point light sources, which are characteristic of anamorphic optics. The Schneider True-Streak Filter simulates this effect without the need for anamorphic optics. It imparts a blue hue to the streaks it creates, closely replicating the colored streaks produced by traditional anamorphic lenses. True-Streak Filters are available in various colors such as red, orange, yellow, green, pink, or violet, and there are also Clear True-Streak Filters that preserve the existing colors of light sources. This particular filter has line patterns spaced 1mm apart. Filters with line spacing of 4mm, 3mm, or 2mm are also available, with the effect becoming more pronounced as the spacing decreases. The Schneider 4 x 5.65" 1mm Blue True-Streak Filter is crafted from water white glass, ensuring clarity and accurate color reproduction, making it a preferred choice among cinematographers and photographers seeking to add distinctive lighting effects to their compositions.
