- lightcraft_catalog::safe_file: one tested helper for crash-safe writes (temp file in the same folder, sync, rename, folder sync; temp removed on failure), write_new/write_new_unique that never replace a file and read the result back, same_file, and a per-thread fault injection for tests. - engine::originals::OriginalGuard: refuses a write whose target is a catalogued photo's original or XMP sidecar (by file identity), whatever the conflict policy or exact path. Used by run_batch (export, Export with Previous, control/MCP exact paths), ui.render/ui.screenshot paths, merge previewPath, MCP render_photo/screenshot paths (new query command export.checkTarget) and lightcraft-cli render. - The conflict policy now covers an export's sidecars together with the file (Unique gives both the same free name, Skip skips when either is taken). - export::write_file replaces the plain std::fs::write in the desktop app, CLI, MCP and engine writers; XMP sidecar writes use the shared helper.

What's new in LightCraft
October 2026
Presets and profiles
- Import presets from other editors: XMP presets, classic
.lrtemplatefiles, "DNG presets" from mobile apps and.zipbundles of any of these — whole folders at once, grouped by pack. Masks inside presets come along. - Luminar looks:
.lmpfiles and.mplumpackcollections import as presets (grouped by collection); the sliders with a counterpart here come along, the rest is listed. - 23 new built-in presets: Portrait, Landscape, Urban, Food, Seasons, Vintage and B&W toners.
Reliability
- Exports and renders never write over a photo's original (issue #93): exporting into the photo's own folder with
the same name and "Overwrite" (or Export with Previous repeating it), an exact output path from the control
channel or MCP, a merge preview path or
lightcraft-cli render IMG.jpg -o IMG.jpgis refused with a clear message, and the original is left byte for byte. Ordinary earlier exports are still overwritten when asked. Exported files are written to a temp file, synced and then renamed into place, so a full disk or an unplugged drive never leaves a truncated file; the XMP sidecar of an "Original" export follows the "If file exists" choice too. - Canon CR2 photos from the EOS 7D, 50D, 60D, 550D, 600D, 1200D, 1300D, 5D Mark II and 1D Mark IV (and other models whose sensor starts on a green-blue row) no longer come out magenta (issue #85): the colour-filter layout is read from each file instead of assumed.
- Exports are never black because of the GPU (issue #78): a GPU render that runs out of device
memory, exceeds the GPU's buffer limits, hits a driver error or reset, or comes back
incomplete is redone on the CPU — the file is the same image either way. Work is sent to the GPU
in short pieces so slow integrated GPUs aren't reset by their watchdog.
ui.inspect→perf(gpuReason,gpuFallback), Help ▸ System Info and Settings ▸ Performance say why the GPU isn't used (e.g. a skipped software adapter such as llvmpipe) and why the last render fell back.
Library
- Smart albums with a rule editor: match all / any / none, nested groups, 26 fields.
- Quick Collection and target album (B in the grid), keyword sets (⌥1–⌥9), colour-label sets.
- Colour-label filter with several labels at once; expandable folder tree in Local.
- Import: copy to any folder, by day / by month / one folder, rename on import, metadata preset, Copy as DNG.
- Import ▸ Move: photos go into the destination (with the same folders and renaming as Copy, e.g.
Photos/2026/20260114/20260114_001.jpg) together with their XMP sidecars; each original leaves the card only after its copy is verified and in the library. Duplicates and files that fail stay where they were. - Watched-folder auto import; Convert to DNG; Duplicate; Build Standard / 1:1 / Smart Previews.
- Export file names use the Rename Photos tokens ({title}, {seq:2}, {date:%Y-%m-%d}…), plus new {num}, {folder}, {lens}, {iso}, {rating}, {creator}.
- Copyright status, rights usage terms and copyright info URL in Info, metadata presets and exports.
- Auto-Tag from Tracklog: GPS locations for your photos from a GPX track log, matched by capture time.
- A change that can't be saved to disk (full or unplugged drive) is no longer silent: the command reports "saved in memory but not written to disk", the top bar shows a warning, and LightCraft keeps retrying until the save goes through.
- Smaller, faster catalogs: photos you only looked at in Local (never added, rated or edited) are forgotten once their folder has not been browsed for 30 days — your files and sidecars stay, and browsing the folder shows them again. Change the period (or turn it off) in Settings → Performance.
Editing
- Auto Sync: edits apply to every selected photo. Auto B&W mix. Automatic versions.
- Colour-range masks: click the photo to sample. Luminance ranges: range bar, smoothness, luminance map.
- ⌘-drag to straighten, ⇧G Guided Upright, a grid while transforming.
Viewing and sharing
- Slideshow, second window, All Metadata, System Info.
- Edit in External Editor (⇧⌘E): a 16-bit TIFF copy, stacked, refreshed when you come back.
- Lossy DNG files and Smart Previews open as raw photos.
- Compressed Nikon NEFs (lossless and lossy compressed, 12- and 14-bit — e.g. D3200, D5100, D7000, D750, D850, Z 50) now develop from the raw data instead of the camera's embedded JPEG, so a B&W or other picture style set in the camera no longer gets baked in. Photos already imported as "preview only" switch over on Reload. (Files that Nikon splits into two differently compressed halves still use the preview for now.)
