The director sold his personal camera for $12.99: Chromagraph sells people, not features
What it is An iPhone camera app sold as a one-time $12.99 purchase that bypasses Apple's default processing and turns RAW into the film color look that Steve Yedlin, cinematographer of Knives Out, designed.
Why it took off Rian Johnson and Yedlin posted about it on X, reaching about 6M views in a day. A dozen-plus tech and film outlets covered it, and the low one-time price drove it to the top of the paid chart quickly. But daily new ratings have already dropped from 117 to 22.
CHow you could follow Don't copy this app; copy the playbook. Find a cinematographer or colorist willing to put their name on it and bring their own audience, turn their style into a one-style one-time-purchase camera, prioritize the Android or video versions it says it won't make, and use the named creator's single coordinated launch to push the paid chart.

Knives Out director Rian Johnson wanted a phone camera that shoots like Steve Yedlin's films. His cinematographer and a color programmer built it in ten weeks. It went onto the App Store on Oct 28, and a week later it hit #3 on the US Top Paid overall chart and charted in 99 countries. The product is genuinely solid, but two people's posts on X pushed it onto the chart. Below: what it sells, where the volume came from, whether you can follow, and if so, which part to follow.
Two posts, ~6M views in a day
Around Oct 28, cinematographer Steve Yedlin posted on X that he, Rian Johnson, and Eric Cameron had built an iPhone camera app. Johnson followed up with the backstory: it started as a private tool he had Yedlin and Cameron build for himself, and he later decided to open it up to everyone. MacRumors 10-30 reported that Johnson's post pulled about 6M views in a day, and user photos shared from the app got thousands of likes.
The App Store reviews spell out where the traffic came from. One US-store user 10-29 wrote: "I purchased this as soon as I saw Rian Johnson post about it"; a UK-store user the same day wrote: "I saw Rian Johnson and Steve Yedlin post it on Twitter".
Then a wave of coverage: Newsshooter, AppleInsider (10-28), Forbes (10-29, headline "Hits No. 1 on the App Store"), 9to5Mac, MacRumors (10-30), a long IndieWire interview (11-03), plus Collider, Gizmodo, GSMArena, and No Film School. The story is the same every time: "Knives Out director made a camera app and hit #1 on the paid chart."
What it actually is
An iPhone camera that only shoots photos, not video, sold as a one-time $12.99 purchase with no in-app purchases or subscription (regional prices: Canada C$17.99, Japan ¥2000, India ₹349). Developer Chromatic Applications LLC has only this one app.
The first line of the store page reads: "Replaces your phone camera's default processing with color and texture designed by Steve Yedlin and used in the Knives Out series." It starts from RAW data and bypasses Apple's image pipeline entirely. The store page stresses that this isn't a filter: "Filters are layered on top of photos your phone has already processed; Chromagraph skips that step." It feels like a film camera: you can't see the final look while framing, only after opening the camera roll. The RAW files are kept, so you can still adjust color, tone, and texture later. Highlight edges get a film-like halation glow, which many positive reviews praise.
The IndieWire interview has a few details useful to anyone following:
- This is a side project. The three people's day job is making lighting-control software for film sets. The camera app was built on the side and finished and tested in ten weeks.
- Yedlin has 20 years of public writing on color science (his site NerdyFilmTechStuff), so the "real color science" claim is believed by people.
- They don't plan to add multiple looks, no Android for now, and video is "still a long way off."
Numbers: one spike, now decaying
Cumulative global ratings (App Store, daily):
| Date | Cumulative ratings | Added that day | Countries charted |
|---|---|---|---|
| 10-30 | 2 | 2 | 86 |
| 10-31 | 59 | 57 | 95 |
| 11-01 | 176 | 117 | 98 |
| 11-02 | 240 | 64 | 98 |
| 11-03 | 299 | 59 | 99 |
| 11-04 | 347 | 48 | 99 |
| 11-05 | 383 | 36 | 99 |
| 11-06 | 405 | 22 | 99 |
11-01 at peak, and each day since has added fewer than the day before. US daily new ratings have dropped from 58 (11-01) to 7 (11-06). The US is now #3 on the overall paid chart and #1 in Photo & Video paid (11-06). Lebanon, India, Canada, the Netherlands, and Thailand are #1 or #2 on the overall paid chart, but these countries have only single-digit ratings, so overseas volume was basically carried by the charts and English coverage.
Revenue is not public. A paid app typically gets 1–3 ratings per 100 downloads, so 405 ratings roughly corresponds to 1.5–40k downloads and $20–500k gross revenue (estimate). It barely entered any country's Top Grossing chart. That doesn't mean it sold poorly; breaking into Top Grossing is hard for one-time-purchase apps anyway.
What users praise and complain about
Positive reviews cluster around "looks like film" and "not a filter," plus the price: "love how it is a one time cost rather than a subscription." Some buyers joke after purchase: "My 18 bucks! Why am I so impulsive?" (18, presumably C$17.99 in the Canada storefront).
Negative and mid reviews cluster too:
- Only one look, few things to adjust: "I'd like… more adjustability to the defaults" (Italy, 4 stars, 11-03)
- Yellow, warm cast, blues handled poorly: "teeth yellow filter" (China storefront, 1 stars, 11-04); "The only thing color wise I don't like is how the blues and rendered" (US, 4 stars, 11-03, as written)
- Rough UI: "UI text is white and doesn't auto-adapt to photo" (US, 3 stars, 11-04); some users can't find the 2x lens
- No video, occasional crashes
Who it's competing with
"Bypass iPhone processing, output from RAW" has been done before:
| Product | Scale (US store ratings, 11-06) | Difference from Chromagraph |
|---|---|---|
| Halide Mark III(Process Zero,2024-08) | 13,678 | Also bypasses Apple's processing, but gives you a clean negative to grade yourself; Chromagraph gives a fixed, named look |
| Leica LUX(2024-06) | 8,045 | Sells "Leica feel," subscription-based; the closest approach, with the brand rather than a person as the selling point |
| Kino (same company as Halide, 2024-05) | 2,000,$9.99 | Shoots video |
| Dazz Cam, Huji, OldRoll and other film emulations | Dazz 117k | Filters on already-processed photos, free with in-app purchases, built for the mass market |
| VSCO, Lightroom | 278k / 339k | Edit after you shoot, subscription |
| Apple's built-in Photographic Styles, ProRAW | Every iPhone | Free, but still runs through Apple's pipeline |
So Chromagraph has nothing new technically. The only new thing is a famous cinematographer's hand-tuned, signed style, backed by the director himself. The features make users feel the one-time price is worth it; the people bring the traffic.
As of 11-06, we haven't seen any copycats cashing in on the name on the App Store or Google Play.
If it were you
Verdict: You can't copy this app. Its traffic comes from Rian Johnson and Steve Yedlin, names a follower can't get. Press coverage has already saturated, and the spike is fading. What's worth taking is the playbook: "one craftsperson's taste, packaged as a one-time-purchase camera with a single style", plus the parts it said it won't do.
Who it suits: You already know a photographer, colorist or film lab person with real credibility in the field, who will put their name on it and post about it on their own account. Or you have the imaging pipeline and RAW processing skills yourself.
Who it doesn't suit: Anyone without a person like this, who just wants to make "another cinematic filter." Without a named person, you're just another filter app between Dazz and VSCO, and you won't break into the paid charts.
How to do it:
- Find a person, not a feature. A photographer or colorist with work and followers on Instagram or YouTube turns their style into one fixed preset, sold as a one-time purchase at $9.99–14.99. Copy the story: "A tool I made for myself, now open to everyone."
- Do what it said it won't: an Android version (officially ruled out for now; the hard part is inconsistent RAW support across phone models, so start with a few flagships), a video version (Halide's Kino proves people will pay for this). Or switch languages: markets like Japan and Korea, with strong photo cultures and high willingness to pay, with a local photographer as the named face.
- Address its bad reviews: a wider range of adjustments, fixable color temperature, UI that adapts to light and dark photos, and support for all lenses.
How to get users: Rely on one concentrated launch, not long-term paid acquisition. On launch day the named person posts with sample shots and a story. Pitch photography and tech press at the same time. Breaking into the Top Paid chart becomes its own news hook. The Top Paid bar is far lower than the Top Free one: a few hundred sales a day can probably put you near the top of your category (inferred). Before launch, run a small beta (Chromagraph did too), and have those users post their photos and reviews on launch day.
How long you have: The buzz around "celebrity or craftsperson-signed camera" probably has two to three months left (inferred). Copycat "cinematic-style RAW camera" apps using the same keywords will show up fast. If you're doing an Android version or a different language, aim to launch before next spring.
What would mean you got it wrong: If Chromagraph ships Android or video itself before December, this gap is gone. If its daily new US ratings stay in the double digits past mid-November, the product itself keeps people, and what you should learn is its color science, not its launch. If the person you pick posts and the app still can't reach the top 〜20 of its paid category within 48 hours, their name doesn't carry enough weight, and this route isn't worth more spending.

Why Chromagraph Camera (ios_6803329435) took off
In one line: this is a paid RAW photo app for iPhone, sold as a one-time purchase at $12.99, made by director Rian Johnson (Knives Out, The Last Jedi) with his longtime cinematographer Steve Yedlin and color-science programmer Eric Cameron. It was driven almost entirely by celebrity reach: two posts on X brought about 6M views in a day, followed by a wave of tech and film press. The "cinema-grade color" claim is real, but that alone wouldn't produce this scale.
1. Data (appstore library, as of 2026-11-06)
- Developer: Chromatic Applications LLC, with this one app on the account. The store lists the release date as 2026-10-20, while the public launch was 10-28 (per Newsshooter's 10-28 coverage and Yedlin's X launch post). The earliest review in the library is also from 10-28, and one says "I was in the beta."
- Global ratings: 10-29 on 0,10-30, 2,10-31 on 59,11-01, 176,11-06 on 405. Daily new ratings peaked on 11-01 (117), then fell to 64, 59, 48, 36 and 22, a clear decline. Countries charting went from 50 to 99.
- US store: 179 ratings (+178 in the last 7 days). Now #3 on the overall Top Paid chart and #1 on the Photo & Video Top Paid chart. US daily new ratings ran 44 (10-31) and 58 (11-01), then dropped to 7 (11-06). UK 34, Japan 24, India 16, Canada 15, Brazil 15.
- #1 or #2 on overall Top Paid in several countries (Lebanon, India, Canada, Netherlands, Thailand and others). Almost no country has it on Top Grossing. Only Nepal (#194) and Russia (#192) do. Top Grossing is hard for one-time-purchase apps to reach, so this doesn't show their revenue is low.
- Tiered pricing by region: US $12.99, Canada C$17.99, Japan ¥2000, India ₹349. No in-app purchases, no subscription.
- Revenue estimate (unverified): a paid app typically gets about 1–3 ratings per 100 downloads, so 405 ratings means roughly 1.5–40k downloads and gross revenue of about $20–500k. This is an order-of-magnitude estimate only.
2. Competitors
| Competitors | Platform | Launched | Scale (appstore library, US, 11-06) | How Chromagraph differs |
|---|---|---|---|---|
| Halide Mark III (with Process Zero) | iOS | 2017;Process Zero 2024-08 | 13,678 ratings, +35 in the last 7 days, #145 in Top Grossing for its category | Also bypasses Apple's processing and shoots from RAW, but gives you clean negatives to grade yourself. Chromagraph gives one fixed, author-signed cinematic style. |
| Kino(Lux Optics) | iOS | 2024-05 | 2,000 ratings, $9.99 | Shoots video, from the same company. Chromagraph shoots only photos. |
| Leica LUX | iOS | 2024-06 | 8,045 ratings, +7 in the last 71 days | Sells the "Leica look" of a premium camera brand as the selling point, on subscription. The closest "brand style" approach. |
| Blackmagic Camera | iOS / Android | 2023-09 | 24,508 ratings | A free professional video camera with a completely different positioning |
| Dazz Cam, Huji, OldRoll, ProCCD, Hipstamatic and other film / CCD emulations | iOS / Android | 2009–2022 | Dazz 117,405 ratings | All apply filters to Apple-processed photos and go for the mass market. Chromagraph explicitly pitches "NOT A FILTER." |
| VSCO, Lightroom | iOS / Android / web | 2013–2014 | VSCO 278k, Lightroom 339k ratings | Post-production color with preset packs, on subscription, edited after you shoot |
| Apple's built-in Photographic Styles and ProRAW | Big-company features | New Styles starting with iPhone 16 | On every iPhone | Free, but it still runs through Apple's processing pipeline |
| Moment Pro Camera II, Very Good Camera, ROLLIE'S and other paid cameras | iOS | 2025–2026 | Ratings sit in the tens to hundreds | Small-team paid cameras with no celebrity backing |
Verdict: "bypass the iPhone's processing and shoot from RAW" has been done before; Halide did it 2024 years ago. Chromagraph's only new thing is a famous cinematographer hand-tuning a credited, single "look", plus the director's endorsement.
3. Growth tactics (evidence)
- Founders and celebrities post on X (confirmed, main channel): Yedlin posted on X "Me and @rianjohnson and Eric Cameron made an iPhone camera app" (X); Johnson also posted an origin story (X). MacRumors says Johnson's launch post got about 6M views, and user photo posts got thousands of likes (MacRumors 10-30). Reviewers say outright they saw it on X: "I purchased this as soon as I saw Rian Johnson post about it" (US store, 10-29), "I saw Rian Johnson and Steve Yedlin post it on Twitter" (UK store, 10-29).
- Press coverage (confirmed, second wave): film and photo outlets include Newsshooter (10-28), No Film School, a long IndieWire interview (11-03), Slant and Collider; tech outlets include AppleInsider (10-28), Forbes (10-29, headline is literally "hits No. 1 on the App Store"), 9to5Mac and MacRumors (10-30), Gizmodo, GSMArena hands-on, Yahoo Tech, iLounge and BroBible. The coverage mostly tells the same story: "director builds a camera app, hits No. 1 on the paid chart."
- The chart flywheel (inferred): after reaching No. 1 in the US overall paid chart and its category, it got covered as "blowing up," creating a second wave of exposure. It charted in 99 countries, but most have only single-digit ratings, which suggests the overseas reach came mainly from the charts and English-language press.
- TikTok and organic creator content (confirmed, small volume): a TikHub search for "chromagraph camera" turns up @kaylamaclay (about 10k views), @danielgrindrod (about 7.5 thousand), and Thai and English tech accounts retelling it, each in the thousands to tens of thousands of views. The official account is @chromagraphcamera. This channel hasn't been scaled yet.
- Paid ads: metaads and tiktokads show no ads from this company (those databases only track products on their watchlists, so no hits doesn't mean no spend); the timeline doesn't look like paid acquisition either.
- Beta users: reviews mention joining the beta (10-28), so there was a small group of seed users before launch.
4. Why it took off
- Celebrity distribution was decisive: ratings surged within 48 hours of the launch post, reviews quote the tweets directly, and every press headline carries Rian Johnson's name.
- The story is easy to tell: "a director had his cinematographer build a private camera for his phone, then opened it up to everyone." It reads as sincere and anti-commercial, and it taps into long-running frustration with computational photography on the iPhone (9to5Mac explicitly framed it that way).
- Price and friction are right: $12.99 one-time purchase, no subscription, so the bar for an impulse buy is low (reviews include "love how it is a one time cost rather than a subscription" and "My 18 bucks! Why am I so impulsive?"). One-time paid apps climb the paid chart easily.
- The product is actually good: many positive reviews say the highlights look like film and "not a filter"; Yedlin has 20 years of public color-science work (NerdyFilmTechStuff), so the "real color science" claim is credible.
- But retention and word of mouth are at risk: negative reviews focus on no video, a yellow or warm cast, only one look, rough UI and crashes. Daily new installs fell from 117 to 22, which looks like a launch spike followed by decay.
5. Differentiation
- The core differentiator is "a single look with a named author" plus "RAW-pipeline processing, not a filter". Competitors either give you freedom (Halide, Lightroom) or filters (Dazz, VSCO). Chromagraph gives you one authority figure's taste, and deliberately offers only one look (IndieWire interview: no plans for more looks, no Android in the short term, video is far off).
- Is that why it broke out? Partly, but not the main cause. Technically, Halide's Process Zero did the processing bypass two years earlier; what made people pay was Yedlin's and Johnson's names vouching for the look. The differentiation made the celebrity recommendation more than a gimmick: buyers got it home and felt it was worth it, which is why early reviews were strong. But the traffic came from people, not features.
6. Visibility and copycats
- Visibility: widely discussed. Evidence is the X post with 6M views, plus Forbes, MacRumors, 9to5Mac, IndieWire and a dozen other outlets. Revenue is not public (no TrustMRR listing, and the founders haven't posted numbers).
- Copycats: the appstore database turns up no apps with Chromagraph or Yedlin in the name; new camera apps since October (Flipcorder, Snapshots, Very Good Camera and others) have very few ratings, so they don't count as copycats. Nothing similar on Google Play either. For now there are no obvious copycats, but "master colorist's look plus RAW" is easy to imitate, and expect "cinematic RAW camera" knockoffs soon.
7. Takeaways
- "Credited taste" can be sold as a product: find a credible craftsperson (cinematographer, colorist, designer), turn their method into one fixed look, price it as a one-time purchase, and tell the story of "the tool I built for myself."
- A one-time paid app can climb the overall paid chart on a single concentrated burst of social and press attention; the paid chart is much easier to reach than the free chart. But prepare a second wave in advance (updates, video, more looks or presets), or the spike will decay.
- The demand in the negative reviews is the opportunity: a video version, the ability to save multiple presets, an Android version, even though the company has said no Android in the short term.
8. Uncertain
- Real downloads and revenue (only rough estimates inferred from ratings).
- Where it levels off after the decay; whether Apple has featured it (not found).
- How much of the X views is bots (someone on the MacRumors forums raised this).
- The overall volume of user photos shared on TikTok and Instagram; no systematic count.
