What film emulation LUTs are, how they work, and what makes the most popular film looks distinctive: Kodak Portra 400, CineStill 800T, Kodachrome and Tri-X, plus tips for using them on digital photos.
Film photography never really went away, and its look is everywhere: warm skin tones, soft highlights, slightly faded shadows. But shooting film is expensive and slow.
Film emulation LUTs let you get close to those looks from digital photos. This guide explains how they work and what makes the most popular film looks distinctive.
A LUT (look-up table) is a map from one set of colours to another. For each input colour, it says "turn this into that".
A film emulation LUT is built to mimic how a specific film stock renders colour and contrast. It doesn't add grain, halation or dust by itself, so the best results combine a LUT with those textures.
The go-to for portraits and weddings.
Use it for: portraits, golden hour, lifestyle, fashion.
Kodak motion picture film adapted for still cameras, balanced for tungsten light.
Use it for: night streets, neon, concerts, cinematic moods.
One of the most famous colour films ever made. Kodak ended production in 2009.
Use it for: travel, street photography, anything mid-century.
The classic black-and-white film of photojournalism.
Use it for: street, documentary, gritty portraits.
A LUT expects a reasonably balanced input. Correct the basics before applying it.
Many LUTs look best at 50–80%. Dial it back until it feels natural.
Pair the colour with:
CineStill 800T on a midday beach can look odd. Portra on neon night streets can look muddy. Pick a look that suits the scene.
Use the same look across a gallery or feed so it feels like one roll.
Bitgrain includes 38 film and cinematic LUTs, including Portra 400, CineStill 800T, Kodachrome and Tri-X, along with grain, haze and bloom you can stack on top.
It also reads around 30 camera RAW formats (Canon, Nikon, Sony, Fuji and more) plus iPhone HEIC and DNG, so you can start from your original files. Editing runs locally in your browser.
A simple recipe:
Film emulation isn't about faking film perfectly. It's about borrowing the colour decisions that made those stocks loved, and applying them with intent.
Try the same photo with Portra, CineStill and Tri-X in Bitgrain. You'll quickly see which one fits your style.
