I spent a weekend about three years ago building a preset pack from scratch. Forty presets, each one named after a song, each one tweaked until it felt like something rather than just something adjusted. I ended up giving the whole pack away for free. It got 50,000 downloads, which still feels unreal when I think about it. But the presets that got downloaded the most weren’t the moody cinematic ones or the clean bright-and-airy edits. They were the ones I’d labeled with names like “Kodachrome Sunday” and “Grain & Settle” — the ones that were doing some version of film emulation.

That told me something. Photographers aren’t just chasing a look. They’re chasing a feeling that digital capture, by default, doesn’t deliver.

What Digital Sensors Actually Get Wrong

Modern camera sensors are extraordinarily accurate. That’s the problem. They render light with a kind of clinical flatness that our eyes don’t experience and our brains don’t remember. When you shoot RAW and open the file in Lightroom, you’re looking at linear light data — a technically correct representation of what was in front of the lens, with no tone curve, no color bias, no character.

Film was never accurate in that way. Kodak Portra 400 skews warm in the shadows and compresses highlights so that blown-out skin still looks like skin. Fuji Velvia saturates greens and blues past what’s literally there, which is why landscape photographers loved it. Ilford HP5 in black and white has a grain structure that’s random and organic, not the digital noise pattern your sensor produces at ISO 3200. These weren’t flaws. They were the medium doing something interpretive with light, and we grew up calling that look “a photograph.”

Film emulation is the process of reverse-engineering those interpretive choices and baking them into your digital files.

The Technical Layers Underneath a Good Emulation

A convincing film emulation isn’t a single slider. It’s at least four separate adjustments working together.

First is the tone curve. Real film has an S-curve response, but it’s not the generic S-curve in Lightroom’s Point Curve panel. Negative film lifts the blacks (nothing in analog is pure zero), compresses the highlights before they clip, and sometimes has a slight shoulder on the shadows that makes them feel dense rather than dark. In Lightroom, you’re rebuilding this in the Point Curve. I typically set the black point anchor somewhere between 10 and 20 on the output axis, and flatten the top of the curve so highlights roll off rather than clip.

Second is color calibration. Each film stock has a color bias built into its dye layers. You can simulate this using the HSL panel for hue shifts and the Color Mixer in Camera Raw to push specific ranges. Portra’s warm shadows, for example, respond well to adding red and pulling back cyan in the shadow-targeted color grading wheels under Color Grading in Lightroom Classic.

Third is the color profile. Lightroom lets you choose a camera profile in the Camera Calibration panel (or the Profile Browser in the Develop module). Switching from Adobe Color to Adobe Landscape or a custom ICC profile changes the base rendering before any of your other edits apply. VSCO, RNI Films, and Replichrome all sell profile-based film packs that start at around $20 to $60 and load directly into this panel. They work because they’re operating at the profile level, not just as an overlay.

Fourth is grain. Lightroom’s Grain tool under Effects is genuinely good now. For 35mm emulation I usually land around Size 25, Roughness 60, and Amount anywhere from 15 to 35 depending on the ISO of the simulated stock. The key is that grain should interact with the image tonally, appearing more visible in the midtones and less so in deep shadows, which Roughness helps control.

Before and After: The Same Portrait, Two Worlds

Take a portrait shot on a Sony A7IV at ISO 400, flat light, RAW file opened with the default Adobe Color profile. Out of the box, the skin is neutral-accurate, the background is clean, and the whole image reads as “digital photograph.”

Apply a Portra 400 emulation, which means lifting blacks to 15, warming the shadows in Color Grading (+15 hue toward orange, +10 saturation), shifting the skin tone hue in HSL slightly warm, loading a Portra-matched camera profile, and adding grain at Size 22, Roughness 55, Amount 20. Same exposure. Same crop. Completely different emotional register. The image stops reading as “captured” and starts reading as “remembered.”

That gap, between captured and remembered, is the entire argument for film emulation.

When Emulation Goes Wrong (And Why Presets Aren’t Enough)

The single biggest mistake I see is applying a film preset without adapting it to the source image. Presets are starting points, not finished edits. A preset calibrated on a warm afternoon shot will look muddy applied to a blue-hour image. The Portra lift on the blacks might push a dark indoor portrait into looking underexposed rather than filmic.

What you’re after is understanding what each layer of the emulation is doing so you can dial it back or compensate elsewhere. If the grain is too heavy for a medium-format simulation, drop the Amount to 8 or 10. If the highlight rolloff is flattening your subject’s eyes, bring the whites back up +15 after the curve is set. Presets teach you the destination. The controls teach you the route.

I built those 40 presets by learning every route first. That’s why they worked.

The goal with film emulation is never to make a digital photo look like it was shot on film. The goal is to make it feel like something a human took, not something a sensor captured.
