Three things were wrong on a 390px phone, and all three cost the photo its screen. The toolbar's six labelled buttons wrapped to three lines (141px of an 844px screen, 17% of it) and now sit on one 30px row of icons; the histogram read as an empty white plot; and a crop corner was a 9x16px target to a touch, so a thumb a few pixels off it moved the frame instead of resizing it. The toolbar keeps its labels in the DOM and only takes them out of the paint — font-size 0 on the button, the glyph on ::before — so every button keeps the accessible name it always had, and the two toggles still report their own state. Verify: measured on a 390x844 viewport with a real P1010256.JPG, the row is 30px tall, one row, buttons 34x30, `fontSize` 0px, the labels still in the DOM as text, and hist-toggle still flips aria-pressed both ways. The histogram was two separate faults, and the first one was invisible to the DOM. Measured: after upload or after a close/reopen the plot is an empty frame for ~100ms (4 paths land at 104ms / 126ms) — that is the mount, not a bug. But the SVG then carried four full-length paths whose own map was flat: the lum curve sat 0.9 of the panel high on ONE bin and every other bin measured 0.066 or less, so the photo read as a line along the floor. That is real: the sampled frame has 34% of its pixels on bin 255, and under a linear scale a blown sky owns the whole panel. The scale is log1p now — an empty bin still sits exactly on the floor — and the bins go from 1 bin above half to 226. The second fault was the paint: `.hist-ch` screens its three curves, which is how light adds up on a dark panel, and it is measured against the backdrop — so on the light theme (a white plot) it screened every channel straight to white. Screen is now gated to `[data-theme='dark']`; measured on the light theme, the plot went from 52 red / 39 green pixels to 931 / 1143 with the grey fill under them. The crop corner keeps its 16px square, which is the size a corner reads at, and grows only its touch target: 44px centred on the node, so the outward half is clipped by the photo's own layer and the target never overlaps the rect it would otherwise hand the drag to. Measured: 23x44px reachable around each node, and a drag from the bottom-right corner's centre still resizes (w 358 -> 297, h 201 -> 167) without moving the frame. Verified: `npx tsc --noEmit` clean, `npm run build` clean, and every number above read back off the built bundle in a 390x844 mobile context. Co-authored-by: PenguinHarness <noreply@penguin.local>
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
