Three narrowband exposures are decoded and merged via merge_rgb_triplet() into a single combined 16-bit TIFF. No sensor correction (not applicable to narrowband captures). WB and device metadata from the primary exposure. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Stitch composites are decoded per-part with flatfield and sensor correction applied before assembly (clean seams, no channel crosstalk). Stitch + RGB-scan triplet combinations supported: each part can be a triplet, producing one TIFF from all source files. Triplet parts skip sensor correction (no leakage with narrowband exposures). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Optional checkboxes (WB, flatfield, sensor correction) let users bake corrections into camera RAW linear exports. All default to off (raw dump philosophy). Hidden for Pakon/DNG sources where they don't apply. Stitch composites always apply flatfield + sensor per-part regardless. Warning hint shown when any correction is active.

Cameras report RGGB quads where G1 and G2 can differ slightly. Averaging both greens for the normalization denominator matches what the demosaiced green channel represents (interpolated from both CFA positions). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

@marcinz606 The stitch+triplet combo path (e.g. 4-part stitch of triplets = 12 files → 1 TIFF) is only covered by synthetic tests — I didn't have the triplet + stitch files raw files to test it for real. You might have some files handy from when you built that feature, could you give it a spin? |

What
Three additions to the Linear Output export (#722):
Composite sources — Linear Output now handles multi-file sources:
Correction toggles (camera RAW only) — three checkboxes to optionally bake corrections before writing:
Testing
27 new tests (79 total): 8 triplet, 8 stitch, 11 corrections.
Verified with real Nikon Z f NEF files (single frame and stitch composite).
