robmdunnandClaude Opus 5.5 6178021107 LR-IMP-CAMERA-COVERAGE: measured image area for Nikon bodies without CropArea 
Nikon bodies from before ~2016 record no CropArea, so the decoder kept
their whole sensor data, less trailing dark columns. Where that data
holds masked lines above black or optical black, they were developed as
a coloured or dark bar on that edge: the D7000 and D5100's 36 columns at
~600 (#976), the D800's 14 (#914, the top in portrait), and others.

MEASURED_BODIES (crates/raw/src/vendor/nef.rs) now gives 36 model /
data size / depth groups the frame of their camera JPEG inside the data:
D7000, D5100, D800, D800E, Df, the D4's 12-bit mode, D3, D3S, D700,
D300, D300S, D600, D610, D810, D4S, D5600, Coolpix A, D3000, D40X, D60,
D80 and D2Xs. An entry matches model, data size and depth exactly; the
measured white level becomes optional (only the D4's 14-bit mode has
one). Bodies whose data holds only picture beyond the camera frame get
no entry and render as before.

`cargo xtask raw-frame FILE...` (crates/engine/examples/raw_frame.rs)
measures a body: it aligns each raw's embedded camera JPEG with the
sensor data (half-size luminance, gradient correlation, sub-pixel peak;
weak, ambiguous or between-pixel peaks are flagged), counts the edge
lines that hold no picture and reports what the decoder's crop keeps
beyond the camera frame. It prints entries only with evidence: at least
3 clean files agreeing exactly, of the model (12- and 14-bit pooled) or,
with at least one of its own, with sibling models of the same readout
(data and JPEG size) that agree on the same frame. On the D7500, which
records its CropArea, it finds that area exactly; it declines the Z f,
whose JPEG is distortion-corrected.
It works for any make whose raw embeds a full-size camera JPEG: on
Sony, Canon CR2 / CR3, Pentax and Samsung files it finds the decoder's
own crop (relative to the active area).

docs/nikon-bodies.md surveys every Nikon raw on raw.pixls.us (98
models, 291 files; 138 CC0 samples measured): 22 models record
CropArea; of the 88 groups without it, 36 have entries, 13 are fine, 25
could not be aligned and 7 do not decode. The D3200, D3100, D200, D50,
D750 and Nikon 1 V1 / V2 are pending, each listed with the files it
needs; the doc also describes how to add a body. raw-parity.md no
longer claims every NEF coding but HE decodes.
measured_bodies_are_consistent checks every entry lies inside its data
and is listed once.

The evidence is committed in docs/nikon-bodies/: headers.json (every
file's raw size, depth and maker-note crop tags), samples.json (the 138
measured CC0 files with URL and sha256) and frames.jsonl (the tool's
per-file results). `cargo xtask corpus --download nikon` fetches the
samples (sha256 checked) so `cargo xtask raw-frame` reproduces every
count.

Raw Blame History

Nikon bodies: sensor data, image area and edge bands

Last updated: 2026-10-11 · Change: created (every Nikon raw on raw.pixls.us; 138 CC0 samples measured with cargo xtask raw-frame) · Scope: Nikon NEF / NRW

Nikon raws hold more sensor data than the picture: a few lines of extra picture around the camera's own frame and, on many bodies, optical black or masked lines that are not picture at all. Newer bodies record the picture's area in the maker note (CropArea, 0x0045) and LightCraft crops to it. Older ones record nothing, so the decoder keeps the whole data (less trailing dark columns), and masked lines inside it are developed as a coloured or dark bar on that edge (#976, #914). Such a body gets an entry in MEASURED_BODIES (crates/raw/src/vendor/nef.rs): the frame of its camera JPEG inside the data, applied only to that model, data size and sample depth. Bodies whose data holds only picture beyond the camera frame get no entry and render as before.

Summary

  • Record CropArea: 22 models, 53 data sizes: handled.
  • Without CropArea: 66 models in 88 groups (model, data size, depth), plus 7 groups without a CC0 sample:
    • measured entry (cropped to the camera frame): 36
    • fine (only picture beyond the camera frame): 13
    • bar, pending more files: 3
    • dark lines, pending more files: 4
    • no clean alignment: 25
    • not decoded: 7

Status: ✅ measured entry · ✅ fine (a few extra pixels of picture) · ⚠️ bar (masked lines inside the crop: a coloured or dark edge) · ❓ check (dark lines inside the crop: optical black, or shadow in that sample) · ❓ unmeasured (no clean alignment: a compact's JPEG is distortion-corrected, or the samples are soft or dark) · not decoded (a raw variant LightCraft can't read yet).

Pending

Bodies whose crop keeps lines without picture but that lack the evidence for an entry (see Adding a body). Each needs more files with detail across the frame, from raw.pixls.us or contributed (any licence: only the measurement is committed, never the file).

Bodies without CropArea

One row per model, sensor data size and sample depth (each covers the compression modes listed). Frame: where the camera's full-size JPEG sits in the data and how many measured files agree (bit depths pooled). Files: samples of the group on raw.pixls.us. Sample: the first file measured, in corpus/raw/nikon-inventory/.

Adding a body

  1. Gather files of the body: several per data size, with detail across the frame (a blank sky, fog or a lens cap has nothing to align on), shot with in-camera distortion control off.
  2. Run cargo xtask raw-frame FILE…. It prints, per model and data size, how many files align cleanly on the same frame and, once there is enough evidence, the MeasuredBody lines.
  3. Evidence: at least 3 clean files that agree exactly, either of the model itself (12- and 14-bit pooled: both read out the same area), or at least one of its own plus siblings, other models with the same readout (data size and JPEG size) whose own files agree on the same frame. The same data size alone is not enough: the D200 and D80 share 3904 × 2616 data but frame it at (16, 12) and (14, 9).
  4. Add an entry only when the decoder's crop keeps lines without picture (edge bands and beyond the camera frame in the tool's output), paste it into MEASURED_BODIES with a comment naming the evidence, and update this file. measured_bodies_are_consistent checks every entry lies inside its data and is listed once.

How this survey was made, and how to reproduce it

The evidence is committed next to this file, in nikon-bodies/:

  • headers.json: every Nikon raw on raw.pixls.us (index of 2026-10-11, 291 files) with its URL, sha256, raw image size, depth and compression and the maker note's CropArea, CropHiSpeed and NEFCompression, read from the first 1 MB of each file.
  • samples.json: the 138 CC0 files measured: one per model, data size and depth without CropArea, and every other CC0 sample of the groups that showed lines without picture (URL and sha256 each).
  • frames.jsonl: cargo xtask raw-frame --json on those files: frame, score, margin, edge bands and what the decoder's crop keeps beyond the frame.

To reproduce, or to re-measure after a decoder change:

cargo xtask corpus --download nikon   # 138 files, ~2.7 GB, into corpus/raw/nikon-inventory/ (sha256 checked)
cargo xtask raw-frame corpus/raw/nikon-inventory/*.* corpus/raw/nikon-inventory/extra/*
cargo xtask raw-frame --json corpus/raw/nikon-inventory/*.* corpus/raw/nikon-inventory/extra/* > docs/nikon-bodies/frames.jsonl

The first raw-frame prints each group's verdict and MeasuredBody entries; the counts in the tables above are its output. Only CC0 files are listed; the D4's 14-bit entry comes from its contributor's own measurement. The statuses above reflect the decoder with this file's entries.
