The live view is the one place where the look is chosen before the picture exists, so the columns that hold it have to stay in reach while the camera is open. The viewfinder was a fixed black sheet over the whole app: the rail and every slider were behind it, and the only way to change the look was to close the camera, grade the file, and open it again. It now covers the stage and nothing else — the stage and the view share a slot (`.stage-slot`, position relative) and the view is absolutely placed inside it, z-index 5, black in either theme. Measured at 1600px: the rail and the columns are on screen, the feed takes 1347px of the 1600 and the stage's own 253px rail the rest. A slider moved with the camera open reaches the very next frame (the render loop reads the recipe per frame, so nothing had to be wired), a monochrome sim takes the live feed from sat 42.1 to 0, and the shutter hands the studio that same frame with the sim already on it. The preview render is skipped while the viewfinder is up (`|| shooting` in the guard, and in the effect's deps): it would run the same recipe through the same renderer as the frames the user is actually watching, and the live one wins. Opening it is PRO, like the HSL chips and the geotag — the frames are the paid ones. The button stays on the page for everyone and carries the badge, and the click runs the app's own `promptPro`: the account dialog for a guest, the verification panel for a signed-in account, `/api/auth/me` being what says which. A verified account gets the camera; a guest gets `.modal-backdrop` and no `camera-view` at all. Probes: cam-pro-gate (guest sees the badge, the click opens the dialog, no viewfinder; verified opens it), cam-live-edit (rail and columns survive the live view, feed covers the stage, the recipe reaches the live frames and the shot), cam-smoke, cam-renegotiate, cam-close-flip.
RecipesCam
RecipesCam is a camera and photo-editing app built around recipes — reusable
looks that carry a film simulation plus a full set of adjustments. You shoot or
open a photo, dial in a look, and keep it as a recipe you can apply again, share
as a .recipe file, or save to your account.
It ships twice from one repository: a React Native (Expo) app for iOS and
Android, and a self-contained web build under docker/ that runs the same
render pipeline in the browser.
What it does
- Shoot with a recipe applied. Live viewfinder, GPS-tagged captures, and the recipe baked into the saved file.
- Film simulations. Built-in looks — PROVIPES, VELVIPES, CLASSIC CHRIPES, CLASSIC NEGIPES, ASTIPES, ETERNIPES, ACRIPES, B&W HIGH CONTRAST and the LC STREETLIFE pair — each with its own grain and tone curve.
- The full adjustment set. Exposure, contrast, highlights and shadows, saturation, colour temperature, clarity, grain, and an HSL mixer with a colour picker that samples straight off the photo.
- Geometry. Crop to a fixed ratio or free-form, quarter turns, and a straighten ruler, plus printed frames (classic border, retro instant, wall frame portrait/landscape).
- Finishing. Watermark and GPS stamp, EXIF carried through the export, JPEG written with a proper 300 DPI JFIF header.
- On-device upscaling. A Real-ESRGAN pass runs locally when an export asks for more pixels than the source has — no server sees the photo.
- Recipes. Save, favourite, export and import
.recipefiles; the web build keeps them in your account, the phone build also keeps them on device.
The two builds
| Build | Where | Stack |
|---|---|---|
| iOS / Android | repo root | Expo + React Native, @shopify/react-native-skia for the render pipeline, NativeWind for styling |
| Web | docker/ |
Vite + React, CanvasKit (canvaskit-wasm) for the same pipeline, Fastify + SQLite API for accounts and recipes |
The render engine is shared by design: the web build compiles the app's own
src/utils/* and type definitions unchanged, with @shopify/react-native-skia
aliased to a CanvasKit shim (docker/frontend/src/engine/skiaShim.ts). A look
looks the same on both because it is the same code.
Running the web build
cd docker
cp .env.example .env
docker compose up -d --build
# → http://localhost:8090
Photos never leave the browser: grading, framing, watermarking and JPEG
encoding all run in the visitor's tab; the API only stores accounts and recipe
JSON. See docker/README.md for the layout and the proxy setup.
Running the app
npm install
npx expo start # Expo Go / dev client
npx expo run:android # or run:ios for a native build
Repository layout
App.tsx, src/ the Expo app: screens, tool rail, viewfinder, shaders
docker/ the web build (frontend + API + compose file)
frontend/shared/ vendored copies of the app's types and utils
