The six starter presets were copied into the photographer's own library on a first run and were theirs from then on. That cannot grow into a real collection: a copy is frozen at the release that wrote it, so an improved preset reaches nobody who had the old one, and re-seeding would overwrite a preset someone had tuned. `dr_pipeline::bundled` now holds the shipped presets as `.drpl` files compiled into the binary, in sections — Essentials (the former six) and three sections of film presets, one per measured stock in dr-film, printed on the paper its profile names — and never writes them to the user's file. Every shipped preset is a look (`Reach::Named`), so applying one keeps the corrections a photograph already has. A name links a photographer's copy to a shipped preset. Saving over a shipped name makes their version the one that name applies; it is listed in the shipped section, marked as changed, and deleting it reverts to the shipped one. Renaming it makes it one of their own and the shipped preset reappears. Keyed on the name because that is what the photographer sees and chooses by. Copies an older first run seeded are forgotten on load where they are still exactly as seeded — otherwise all six would list as changed and stay frozen at their old values. A tuned one is kept and now overrides. The sheet lists "Yours" first, then each shipped section, with headings. Shipped rows apply and nothing else; a changed row offers Revert where the photographer's own offer Delete. A dr-ui test checks every shipped film names a stock this build can bake, on that stock's own paper, because dr-pipeline does not link the profile database. The film presets name stocks by id; the measurements behind them are spektrafilm's (CC BY-SA 4.0), attributed in each file as in dr-film.
Documentation
Two audiences, two folders. Most people want the first table and never the second.
Using DarkRoom
| The manual | Every feature, pictured from the application itself — opening a library, rating, labelling and filing, duplicate originals, developing, local masks, repair, film, panoramas, export. The application carries it and opens it from Help and from Settings |
| How it is driven | Every gesture and shortcut, by screen. Generated from the code, so it cannot describe one the application does not have. The same list is the in-app help sheet: Help or F1 in the grid, ? or F1 in develop |
The top-level README says what DarkRoom is, how to get it on each platform, and what is still missing.
Changing DarkRoom
Everything under dev/ is for someone working on the code. Start with
CONTRIBUTING.md, which says how to land a first change
without reading the rest.
The register and the record. What must be built, how it is built, and how far along it is.
| requirements.md | What the software must do — the numbered register, the decisions (D-numbers) and the spikes (S-numbers) |
| architecture.md | How it is built — crates, the GPU pipeline, the data model, sync |
| traceability.md | Generated: which requirement is claimed by which file. Never edited by hand |
| outstanding.md | What is specified and not built, and whether that is a decision or a gap |
| technical-debt.md | Compromises taken deliberately, each with the condition that retires it |
| code-health.md | What a contribution costs, per seam, measured |
Designs, one per subsystem. Each is the specification the code was built to, kept current as the code moved.
| catalog.md | The index, the library view, incremental scan, the job queue |
| storage.md | Storage backends: the seam a folder, a sync client and a Nextcloud account share |
| faces.md | Face detection, identity, clustering and the eye-state models |
| segmentation.md | How the application finds the regions a local mask snaps to |
| mask-editing.md | Painting, erasing and combining masks |
| spot-removal.md | Clone and heal as parameters in the edit graph |
| panorama.md | Alignment, projection, the chunked composite and the border fill |
| inference.md | The neural runtime and model chosen per device, with the measurements |
| display-and-extension.md | The display contract, and why the fused pipeline is already most of a plugin format |
| view-composition.md | A controller for the display layer |
| ui-navigation.md | Finding things in the interface once there are many |
Measurements. Numbers committed so a regression is a diff rather than a recollection.
| benchmarks.md | The per-commit suite: what it covers, what it does not, how to read a failure |
| bench-baseline.json | The committed numbers the suite checks against |
| frame-budget.md | What a frame costs on each device, and the decision those figures settled |
Platforms and distribution.
| distribution.md | Which channels v1 targets and what each one constrains |
| windows.md | The Windows installer, cross-built from the Linux CI |
| android-signing.md | Which key signs the APK, and keeping it |
Archive. Kept as the record of what was asked for, not as plans.
| milestone-v0.1.md | The first milestone, delivered 2026-08-30 and superseded |
| ui-refinement.md | How the interface should look; succeeded by ui-navigation.md |
Conventions
Three files here are generated and must not be edited by hand:
gestures.md, dev/traceability.md and manual/index.html, the page the
packages install, rendered from manual/README.md. All three come from
cargo run -p traceability, the pre-commit hook keeps them in step with the
tree, and CI fails when one is not what the tree generates. The manual's
pictures are recorded by tools/manual and live
in LFS.
A design document links to the requirements it satisfies and to the code
that satisfies them. When the code moves, the link moves with it; a document
that has stopped being true goes to dev/archive/ with a note saying what
replaced it, rather than being deleted.
