Independent exiftool-parity audit comparing oxidex against a freshly pulled ExifTool 13.55 tag database.
Bug
MakerNotes are the dominant missing-tag category across RAW formats:
- CR2 (Canon): 167 missing MakerNotes tags
- NEF (Nikon): 100 missing MakerNotes tags
- MRW (Minolta): 71 missing MakerNotes tags
- DNG: 138 missing MakerNotes tags
- RW2 (Panasonic): also significant gaps
Total missing tags by format: CR2 240, DNG 200, NEF 137, RW2 123, X3F 117, MRW 72 — MakerNotes account for the bulk of each.
Scope
Proprietary maker-note parsers need substantial expansion to reach ExifTool parity. This is likely multiple follow-up efforts per manufacturer, but filing as one tracking issue for the overall gap; may want to split into per-manufacturer issues once prioritized.
Repro
just compare-exiftool-format CR2 (or DNG/NEF/RW2/MRW/X3F) + uv run scripts/find_tag_gaps.py --only-format <FORMAT>.
