Pulling it off involves careful choreography, framing, focus, lighting, mise en scene, and more. But the trick shot is more than a flex for other DPs and directors to admire. In this video, we dive into all things split diopter, from its uses to some classic examples. HOW TO USE A SPLIT DIOPTER A split diopter is a half-convex lens attachment that allows two subjects at different depths to remain in focus simultaneously. Unlike deep focus cinematography, which requires stopping down the aperture, increasing light levels, and sacrificing background blur, a split diopter creates two separate focal planes in a single frame. To set up a split diopter shot, the first step is determining the composition. The cinematographer needs to position one subject in the foreground and another in the background. Once the shot is framed, the split diopter is mounted onto the camera lens, typically using a matte box. Focusing with a split diopter requires a careful balance. The cinematographer usually will first focus on the subject without the diopter, hen fine-tunes the focus until the second subject also appears sharp. Since split diopters do not increase the depth of field but rather create an artificial division, a soft blur line will appear between the two focal planes. You can minimize this distraction with mise en scene choices. BEST SPLIT DIOPTER SHOTS Split diopters are commonly used when filmmakers need to emphasize two distinct elements in the same frame without losing clarity. Thrillers benefit greatly from this technique, allowing tension to build between a foreground character and an ominous background element. Directors can use split diopters for stylistic reasons, enhancing their compositions with exaggerated depth and distinct focal separations. CREATIVE SPLIT DIOPTER FX Some cinematographers may experiment with removing the diopter mid-shot, requiring a lot of practice and patience. Meanwhile, there are variations on the split diopter. Spot diopters, for example, isolate a single circular area in focus while the rest remains blurred. This effect draws attention to a specific detail without disrupting the overall depth of field. For a while, split diopters were out of fashion, but they're making a comeback. It's a welcome change-- the tool harkens back to iconoclastic directors like Brian DePalma. #FilmTheory #VideoEssay #Filmmaking ───────────────────── ♬ SONGS USED: “Comanche” - The Revels “Chandramukhi Score” - Vidyasagar “Theme from The Conversation” - David Shire “The Paradigm” - Lil Yachty “Citizen Kane Suite” - Bernerd Herrmann “The Good, The Bad, and The Ugly Score” - Ennio Morricone “LUltima Diligenza di Red Rock” - Ennio Morricone “Tsunami” - Jo Blankenburg “Solaris” - Makeup and Vanity Set “Red Handed” - Danny Elfman “Waves” - lwfi “Le vent tourne” - Sensunik “Los Diablos” - Stephen McKeon “Cracking The Russian Codes” - James Horner “Tannhauser Gate” - Makeup and Vanity Set “Theme and Variations From Citizen Kane” - Bernard Herrmann “Don’t Let Me Be Misunderstood” - Santa Esmerelda Music by Artlist ► https://utm.io/umJx Music by Artgrid ► https://utm.io/umJy Music by Soundstripe ► http://bit.ly/2IXwomF Music by MusicBed ► http://bit.ly/2Fnz9Zq ───────────────────── SUBSCRIBE to StudioBinder’s YouTube channel! ►► http://bit.ly/2hksYO0 Looking for production management solution for your film?
