CineStill 800T Film Emulation on iPhone

CineStill 800T is Kodak Vision3 500T motion picture film with the remjet layer removed, and that single act of engineering gives it the most distinctive visual signature of any still photography film stock alive today. The red halation that bleeds around point light sources, the tungsten color balance that turns neon signs into liquid light, the cinematic grain structure — this is film that makes every street corner look like a movie set. REGRADE brings that halation-drenched night look to your iPhone through AI that knows how motion picture film sees artificial light.

What makes CineStill 800T distinctive

CineStill 800T starts life as Kodak's motion picture stock, the same film used to shoot major Hollywood productions. The "T" stands for tungsten — the film is color-balanced for 3200K artificial light, which means it renders tungsten and neon sources with natural warmth while daylight takes on a cool, blue cast. But its true signature is the halation: removing the remjet anti-halation layer (necessary for C-41 processing) allows light to bounce off the film base and re-expose the emulsion, creating a red-orange glow around bright highlights. It is technically a flaw. It is visually spectacular.

• Red-orange halation around point light sources — neon, streetlights, candles
• Tungsten color balance (3200K) that renders artificial light warm and natural
• Cool blue cast under daylight, creating a cinematic teal-and-orange palette
• Medium grain with a cinematic quality inherited from motion picture stock
• High speed (800 ISO) optimized for low-light and night shooting
• The only still photography film that looks like it belongs in a movie

Best for

CineStill 800T was made for the night. Neon-lit city streets, rain-soaked urban environments, concert venues, late-night diners, and anywhere artificial light dominates — this is where 800T comes alive. The halation effect is most pronounced around isolated point lights, so compositions that include streetlamps, car headlights, or illuminated signage will exhibit the signature red glow. Shot in daylight with an 85B filter, it also produces a unique warm-cool split that has its own cinematic quality.

• Night photography and neon-lit urban scenes
• Cinematic street photography after dark
• Concert and venue photography under stage lighting
• Rain and wet street scenes where light reflects and halates
• Any scene where artificial light is the primary or sole source

How REGRADE emulates CineStill 800T

CineStill 800T's halation is the single hardest film characteristic to fake convincingly. It is not a simple bloom or glow filter — it is a light interaction that depends on the brightness, size, and spectral content of individual light sources in the scene. A neon sign halates differently than a streetlamp, and both halate differently than a car headlight. The red-orange color of the halation comes from the specific way light bounces through the emulsion layers, not from a uniform color overlay.

REGRADE captures flat, unprocessed sensor data by disabling Apple's Deep Fusion pipeline, which is critical for 800T emulation because the flat capture preserves bright highlight detail that computational photography would clip or HDR-process. The AI regrading engine identifies individual light sources in the scene and applies halation with source-aware behavior — brighter, more isolated lights get more pronounced halos, while the color shifts from red-orange to softer amber depending on the light's spectral content. The tungsten white balance is applied scene-wide, and the grain pattern uses the specific motion-picture-derived structure that gives 800T its cinematic texture. The result is night photography that feels like it was shot on a film set — because the film stock it is emulating was literally designed for one.
