Three things, all from one look at a folder of TIFF scans. A `.tif` is no longer a RAW. Nothing here develops one, and `tif`/`tiff` sat in `RAW_EXT` for no decoder's sake: opening a TIFF asked for PRO and its tile wore a RAW badge, for a file the engine has nothing to hand back. Both extensions are dropped, and a TIFF keeps its own route instead — the tile reads the file's own pixels (`useThumbUrls`, via `tiffDevelop`) and so does the studio — so a `.tif` still opens and still draws, it just is not a RAW any more. The wall's render loop. `painted` was a fresh `.slice()` on every render, so `useThumbUrls` saw a new list each time round and its effect ran again, and again: about twenty thousand renders a second while the page sat idle, and the file reads frozen at the first screenful, so a tile scrolled to never came up (7 of 24 cards drawn). `painted` is memoised on `listed, wall.from, wall.to` now — no date formats in eight idle seconds, 28 of 28 cards after a scroll. Scrolling between the two modes. SINGLE → ALL THUMBS lands the wall on the frame the strip was showing, centred in the window; ALL THUMBS → SINGLE swipes the strip to the frame nearest the wall's middle, centred in the row. Each way the frame the other mode was standing on is the one you come back to.
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
