CineStill 800T look on iPhone, halation included

26 September 2026

To get a CineStill 800T look on iPhone, you need three things: tungsten-balanced colour, a red-orange glow around bright lights, and grain that stays visible at night. You can build all three into one film and see the result live in the viewfinder. The glow is the part people say can't be faked. It can, because it's a physical effect with rules you can model.

What CineStill 800T actually is

CineStill 800T is Kodak's Vision3 500T motion picture negative, respooled for still cameras. It is sold as CineStill 800Tungsten. Two things set it apart from ordinary colour negative film.

• It is balanced for tungsten light. The film is designed to render light of about 3200K as neutral. Warm streetlamps and bulbs come out clean. Daylight, overcast sky, many LEDs and neon go blue or cyan. That cool, mixed-light palette is most of what people mean by "the 800T look".
• It has no remjet. Cinema film carries a black carbon backing called remjet, which stops light reflecting back off the film base. CineStill removes it so the film can go through ordinary C-41 lab processing. Without it, bright light goes through the emulsion, bounces off the base and exposes the film a second time from behind. The layer nearest the base is the red-sensitive one, so the halo is red-orange. That is halation, and on 800T it is strong.

CineStill rates it at EI 800 in C-41. Kodak rates the underlying 500T at 500. In practice people shoot it at night, wide open, around neon, headlights and shop windows, which is where the halos and the colour both show up.

"You can't do 800T digitally" — a respectful disagreement

In 2021 The Phoblographer published "Want the Look of CineStill 800T in Digital? We've Got Some Bad News". Chris Gampat argued the film can't be duplicated digitally and that film's value lies in doing what digital can't. He also granted that a tungsten white balance gets you part of the way.

The second point is fair. Film is worth shooting for its own sake, and a digital file won't reproduce every quirk of a particular roll, lab and scanner. The first point is harder to defend. Halation isn't mysterious. It follows three rules:

1. Only light above a certain brightness is strong enough to bounce back and re-expose the film.
2. That light spreads out as it travels through the base and back, so the glow is soft and wider than the source.
3. It lands mostly in the red layer, so the glow is red-orange and shows on the darker area around the highlight, not on the highlight itself.

Each rule maps to a control. Chobial's halation takes pixels above a Threshold, blurs them by a Spread set as a fraction of the frame, tints them red-orange and screens them back over the image. That is the same order of events as on the film. For a longer explanation, see what halation is, and how to fake it properly.

Doing it live on a phone also helps at night. On film you learn where the halos went a week later at the lab. With the film in the viewfinder you can see which lights bloom and move a step until a neon sign sits against dark sky rather than a bright wall.

Your options on iPhone

• iPhone 18 Pro's Film texture. PetaPixel's iPhone 18 Pro review says Film applies "a very Cinestill-like level of halation" to high-contrast areas. But Photographic Styles work only on HEIF, not JPEG or RAW. The Verge reports that the texture is limited to photos captured on an iPhone 18 Pro or iPhone Duo. More in our post on the Film texture.
• mood.camera. Its 800T preset is "inspired by the iconic Cinestill", with cool tones, halation and grain. It's a good app, and a sensible choice if you want a ready-made preset.
• The free route. Set Apple's Camera, or any app with manual white balance, to about 3200K and shoot at night. That gives you the colour but not the halos. You can add a glow in an editor later, one photo at a time.
• Build your own film. This is what Chobial is for. You set the colour, halation and grain yourself, see them live, and the photo stays a RAW negative you can develop again.

Recipe: Night Tungsten

This is our own recipe, inspired by the 800T look. It starts from Chobial Negative, a hard-contrast consumer negative with teal greens and deep reds that already suits night streets. Like every recipe here, treat it as a starting point and adjust it against your own photos.

Here is what each part does.

• Temperature −400K moves the develop cooler, the way tungsten film looks under anything bluer than a bulb. It's a mild shift so the film still works on Auto white balance. For the full effect, use a Tungsten white balance in the camera (see below) and the film's shift adds to it.
• Local Tone Mapping 30% reins in the iPhone-style HDR that lifts night skies to grey. On film, a night sky stays dark and the halos glow against it.
• Contrast down, Shadows up, a little Fade soften Chobial Negative's hard curve toward the softer shadow look of 800T scans.
• Split toning pushes shadows toward cyan-teal and warms highlights slightly. Mixed city light on tungsten film tends to look like that.
• No Remjet halation is the preset made for this look. Try No Remjet Heavy if you want the exaggerated halos from the most-shared 800T frames. If the glow spreads onto midtones like lit walls, raise Threshold toward 80%.
• Grain is the 35mm ISO 400 stock pushed a little stronger and coarser, for an 800-speed film shot at night. See why digital grain looks fake for how the grain is shaped.

Doing it in Chobial

1. Open Films by holding the film on the camera, tap + › New Film, and start from Chobial Negative. The Make your own film tutorial walks through each section.
2. Enter the settings above. The preview is one of your own photos, so pick a night shot with lights in it. Hold the preview to compare with the starting film.
3. Save. Night Tungsten is now in the camera's film strip, and on Camera Control if your iPhone has it.
4. Shoot. The film, halos included, shows live in the viewfinder. Touch and hold to see the scene without it.
5. Already have night photos in the library? Open one, choose the Film tool and tap Night Tungsten. It develops again from the RAW. If the halos are too much on that frame, turn Strength down.

Shooting tips for night streets

Set the white balance like the film

800T works by keeping one white balance while the light changes. Open WB and choose Tungsten, or Kelvin at around 3200K. Don't use Auto. Auto white balance keeps correcting towards neutral, and that neutral result is the digital look you're trying to avoid. With a fixed 3200K, sodium and incandescent light render warm-neutral, while LED signs, phone screens and dusk sky go blue and cyan. Mixed-light scenes are where this look is strongest. White balance and the other manual controls are covered in the manual controls tutorial.

Expose for the highlights

Turn on Zebra under DISP. Bring exposure compensation down until the stripes cover only the light sources themselves: bulbs, neon tubes, headlights. Halation needs bright highlights, but if a whole shop window clips, the glow spreads into a wash. The shadows of a RAW file hold more than they seem to on screen. You can lift them later in the Light tool, and the halos stay put.

Frame for the glow

• Put small, bright sources against dark areas: a single neon sign on a dark facade, taillights on a black road, a lamp against the night sky. Halos read on the dark pixels around a highlight.
• Wet streets double every light. Rain is your friend.
• Practical lights inside the frame (a desk lamp, a string of bulbs) give halos in interiors too.
• Slow down. In S mode, 1/30s with the phone braced is usually enough for a still street. The grain hides a little noise.

Know when it won't look like 800T

In flat daylight, a tungsten film with heavy halation mostly looks blue and soft. That's accurate: 800T in daylight looks like that unless you use a warming filter. For daytime shots, load a different film, or re-develop them later with one.
