# LightCraft roadmap
|
||||
|
||||
Milestones toward full Adobe Lightroom parity (cloud Lightroom first, then every Lightroom Classic module), with wall-clock
|
||||
estimates for continuous (24/7) agent-driven development with 4–6 parallel agents. Estimates are calibrated on the sibling
|
||||
projects (DrawCraft reached its first four milestones in ≈ 4½ h) and are revised as milestones land.
|
||||
|
||||
**Status legend:** ✅ done · 🚧 in progress · ⬜ not started
|
||||
|
||||
| # | Milestone | Scope (summary) | Estimate (h) | Status |
|
||||
|---|---|---|---|---|
|
||||
| M0 | Skeleton + visual shell | workspace, xtask CI + layering, geom/color/raster, develop model, pipeline v0, catalog v0, engine commands, Lightroom-look UI (grid, loupe, filmstrip, Edit panel), control channel, MCP, web build | 3–5 | 🚧 |
|
||||
| M1 | Library core | import (JPEG/PNG/TIFF/WebP), EXIF/XMP, persistent catalog (op log + snapshots), albums, ratings/flags/labels, filter/search/sort, thumbnail cache, 100k-photo grid | 6–10 | 🚧 (codecs, meta) |
|
||||
| M2 | Pipeline v1 (quality) | WB temp/tint, profiles, local tone mapping (highlights/shadows), curves, HSL, point colour, colour grading, texture/clarity/dehaze, vignette, grain, B&W, auto tone/WB, histogram, before/after | 10–15 | ⬜ |
|
||||
| M3 | RAW I | TIFF/DNG (LJ92, deflate, tiles, opcodes), demosaic (AHD/PPG/bilinear), highlight recovery, DNG colour model, CR2, NEF, ARW, embedded previews | 10–15 | 🚧 |
|
||||
| M4 | Crop, geometry, optics | crop tool + overlays, straighten, Upright (auto/level/vertical/full/guided), manual transforms, CA, defringe, manual lens corrections | 6–10 | ⬜ |
|
||||
| M5 | Performance | source pyramids, wgpu compute pipeline (CPU oracle), draft/full renders, prefetch, budgets (16 ms slider updates on 24 MP) | 10–15 | ⬜ |
|
||||
| M6 | Masking | brush, linear/radial gradients, colour/luminance/depth range, add/subtract/intersect/invert, all local adjustments, masks panel | 8–12 | ⬜ |
|
||||
| M7 | Detail | sharpening + masking preview, luminance/colour NR, Denoise, Raw Details, Super Resolution | 6–10 | ⬜ |
|
||||
| M8 | Heal / Remove | content-aware remove (PatchMatch), heal, clone, brush spots, visualize spots, red/pet eye | 6–10 | ⬜ |
|
||||
| M9 | Presets, profiles, versions, sync | preset browser + amount, create/import presets, profile browser, versions, history, copy/paste/sync settings | 5–8 | ⬜ |
|
||||
| M10 | Export & share | export dialog (JPEG/PNG/TIFF/DNG/AVIF/JXL/original), sizing, sharpening, metadata, watermark, naming, batch jobs, XMP sidecars, HDR export | 6–10 | ⬜ |
|
||||
| M11 | RAW II | CR3, RAF (X-Trans), ORF, RW2, PEF, SRW, 3FR, IIQ + long tail; camera calibration DB; HEIC/AVIF/JXL import | 20–35 | ⬜ |
|
||||
| M12 | AI & smart features | subject/sky/background/people/object masks, semantic search, faces/People (permissively licensed models, pure-Rust inference) | 20–40 | ⬜ |
|
||||
| M13 | Merge | HDR merge (deghost), panorama (projections, boundary warp, fill edges), HDR panorama | 10–15 | ⬜ |
|
||||
| M14 | Video | import/playback/trim via FilmCraft crates, global edits + presets on video, video export | 6–10 | ⬜ |
|
||||
| M15 | Classic modules | Map, Book, Slideshow, Print, Web; smart collections, stacks, virtual copies, publish services, tethering | 25–40 | ⬜ |
|
||||
| M16 | 1.0 polish | preferences, shortcut editor, accessibility, localization, packaging (dmg/msi/AppImage/web), hardening | 10–20 | ⬜ |
|
||||
|
||||
## Totals
|
||||
|
||||
| Target | Milestones | Wall-clock estimate |
|
||||
|---|---|---|
|
||||
| Cloud-Lightroom feature complete | M0–M11, M13–M14 | **≈ 130–180 h** (6–8 days, 24/7) |
|
||||
| Full parity incl. Classic modules and AI | M0–M16 | **≈ 200–300 h** (9–13 days, 24/7) |
|
||||
|
||||
## Risks that coding hours alone don't retire
|
||||
|
||||
- **AI features** (subject/sky/people masks, generative remove) need model weights with licences we can ship; classical
|
||||
fallbacks first. No permissively licensed sky-segmentation or raw-denoise model was found — we may need to train our own.
|
||||
- **Camera colour and lens data** is a data problem: we never use Adobe's matrices, DCPs or LCPs. DNG-embedded data first,
|
||||
then our own calibration; long-tail camera/lens coverage grows over time.
|
||||
- **Legal decisions pending:** whether GPL-licensed *prose* format descriptions (e.g. the public CR3 write-up) may be read
|
||||
by a designated engineer to produce an internal spec; freedom-to-operate review for local Laplacian filters, PatchMatch and
|
||||
HEVC (HEIC).
|
||||
- **Look parity** with Adobe's default rendering is subjective tuning against our own reference targets.
|
||||
|
||||
## Log
|
||||
- 2026-09-30: roadmap created; M0 in progress; research docs (Lightroom reference, Rust imaging ecosystem) complete.
