The Bayer layout of Canon CR2 files differs by model (GBRG on the 7D, 50D, 60D, 550D, 600D, 1200D, 1300D, 5D Mark II, 1D Mark IV; RGGB on the 40D, 5D Mark III, 6D, 5DS R and others). Read it from raw IFD tag 0xc5e0 (CR2CFAPattern: 1 RGGB, 2 BGGR, 3 GBRG, 4 GRBG), anchored at the full decoded sensor; fall back to RGGB when the tag is missing. No model table. Checked on 35 decoded CC0 raw.pixls.us CR2s (35 models): the tag agrees with the mosaic's green-diagonal statistic on every file; the SensorInfo border parity does not predict the layout. Corpus manifest gains the reporter's samples; a corpus test asserts each layout. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

# What's new in LightCraft
|
|
|
|
## October 2026
|
|
|
|
### Presets and profiles
|
|
- Import presets from other editors: XMP presets, classic `.lrtemplate` files, "DNG presets" from mobile apps and `.zip`
|
|
bundles of any of these — whole folders at once, grouped by pack. Masks inside presets come along.
|
|
- Luminar looks: `.lmp` files and `.mplumpack` collections 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
|
|
- 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.)
