The example file
DSC_0421.JPG · 4.2 MB · 5568 × 3712 · 20.7 MP · aspect 3:2
A DSLR photo transferred directly from a memory card. A "clean" case: camera-original claims with rich, internally consistent evidence.
Summary & provenance reading
Provenance reading: "Consistent with a camera original" — level: neutral-positive. The evidence chips: Rich context · Natural image range · Lossy (DCT) · 5568×3712 · GPS present · Baseline JPEG.
What the report says: EXIF identifies a Nikon D750 with the lens record matching the exposure data; the JPEG structure shows baseline encoding with a single compression pass; no editor strings, no platform traces, no appended data. Together these signals are consistent with a file that came straight from a camera. The report words it exactly that way — consistency, not certification.
Camera & EXIF card
| Field | Value | How to read it |
|---|---|---|
| Make / Model | Nikon D750 | Recorded claim about the capture device |
| Lens | AF-S Nikkor 24-120mm f/4G | Lens record at 35mm zoom position |
| DateTimeOriginal | 2026:08:14 17:42:19 | Shutter time per the camera's clock — a recorded fact, not proof of the moment |
| Exposure | 1/250 s · f/5.6 · ISO 200 | Capture settings; internally consistent with the lens record |
| Software | (none) | No editor has re-saved the file — consistent with camera-original |
Location card
GPS records present: 48.858370° N · 2.294482° E — approximate place resolved as Paris, Île-de-France, France. The report states coordinates as recorded facts and the place name as an approximation. On real reports, the page also discloses that coordinates may be sent to a third-party geocoding service (OpenStreetMap's Nominatim) to produce the place name — the image itself is never sent.
Identity, structure & signals
- SHA-256:
9f2c07a4e1b8d5f3a6c0e9d2b4f7a1c8e3d6b9f2a5c8e1d4b7f0a3c6e9d2b5f8— the file's exact identity; any byte-level change alters it completely. - dHash (perceptual):
f0e1c3870f1e3c78— visual similarity fingerprint, robust to resize/re-encode. - Structure map: APP1(Exif) · APP1(XMP) · DQT · SOF0 (baseline) · DHT · SOS — a clean, camera-typical JPEG layout. No COM comments, no unknown segments, no trailing data.
- Entropy profile: average 79.4 / 100 — "Natural image range". Slices dip at the header (expected) and run flat across the compressed payload. No anomalous regions.
- JPEG quality estimate: ~96/100, single quantization table set — consistent with a camera save, not a web re-encode.
- Provenance markers: none found — no AI generator strings, no C2PA markers, no IPTC source declarations, no editor signatures.
Journey of the file
The Journey section reconstructs a timeline from the signals — presented as a consistency assessment, never an authenticity verdict:
- Captured by a camera — EXIF identifies Nikon D750, taken 2026:08:14 17:42:19.
- No naming or platform patterns — the filename follows a camera default (DSC_…), consistent with a direct transfer from a memory card.
- No re-encode evidence — baseline JPEG, single-pass quantization, no editor or platform strings.
- Metadata fully survived — EXIF, XMP and GPS all intact, consistent with a file that was never processed by a stripping platform.
Classification: "Consistent with a camera original." The report adds the standing caveat: metadata can be forged; a crafted file could reproduce every signal above. That is why the wording is consistency, never confirmation.
Limitations, exactly as the report shows them
Every report closes with the limitations block: metadata can be modified or removed; missing metadata does not necessarily mean manipulation; forensic indicators are not always conclusive; results should be interpreted in context. This sample is no exception — it cannot prove the file came from a camera. It can tell you that every signal the file carries is consistent with that story, and it shows you exactly which signals were weighed.
What a "dirty" case looks like
The sample above is the clean case. On a WhatsApp-forwarded screenshot, the same cards read very differently: camera EXIF absent, GPS absent, dimensions downgraded, progressive re-encode detected, filename matching a WhatsApp export pattern, metadata survival graded "Metadata-light", and Journey classified "Passed through a platform or app". Nothing is flagged as "fake" — the report explains that this pattern is exactly what normal platform processing produces. That calibration between "suspicious" and "normal stripping" is the product's core skill.
