GPS Metadata RateThe proportion of files where this device embedded GPS coordinates — from an on-board receiver or a paired smartphone.
Percentage of files from this device that contained GPS location data.
MakerNote PresenceA proprietary manufacturer block inside EXIF whose format is largely undocumented. Contains settings not in standard EXIF — focus mode, scene detection, lens data, processing flags.
Rate at which this device embeds a MakerNote block (proprietary manufacturer metadata).
Embedded ThumbnailA small JPEG preview stored inside the EXIF APP1 segment, written at capture. May differ from the full image if the file was post-processed.
Rate at which this device embeds a thumbnail in the EXIF APP1 segment.
IPTC Metadata RateInternational Press Telecommunications Council — an editorial metadata standard for captions, copyright, and keywords. Usually added by software rather than written by cameras at capture.
Percentage of files that included IPTC metadata (typically editorial or copyright data).
Composite Image RateAn EXIF flag set on images assembled from multiple exposures — HDR, panorama, focus stacking — or processed by computational photography pipelines.
Percentage of files flagged as composite images in EXIF metadata.
APP14 SegmentAdobe colour transform marker — a JPEG segment storing a single byte that tells decoders how to interpret YCbCr colour channels when converting to RGB.
APP14 (Adobe color transform marker) presence rate.
Restart Interval (DRI) RateDefine Restart Interval — a JPEG marker that splits the compressed stream into independently-decodable blocks to aid error recovery. Canon cameras include it consistently; most others do not.
Rate at which this device writes a DRI (Define Restart Interval) marker. Canon cameras consistently include this; most Nikon, Sony, and smartphone output does not.

SOF Compression TypeStart of Frame marker — identifies the JPEG compression algorithm. SOF0 = baseline DCT (most common); SOF2 = progressive DCT (multiple passes, common in web-optimised images).

DQT Quantisation Table FingerprintsThe 64-value matrix that controls JPEG lossy compression. Baked into firmware — consistent across units of the same model — and distinctive enough to act as a camera fingerprint.
JPEG quantisation table fingerprints. Identical patterns across devices indicate shared hardware or firmware lineage.

JPEG Segment InventoryThe set of JPEG markers consistently present in output from this device. Marker presence and order are firmware-determined and can help distinguish camera lineages.
APP and SOF segments consistently present in output from this device.
| Observed value | |
|---|---|
| SOIStart of Image — the 2-byte marker that opens every valid JPEG file. | |
| APP1Primary metadata container — holds EXIF camera data (make, model, GPS, settings) and optionally XMP. | |
| DHTDefine Huffman Table — the compression lookup table baked in by the encoder. | |
| DQTDefine Quantization Table — the 64-value lossy compression matrix. Consistent per firmware; useful as a fingerprint. | |
| SOSStart of Scan — marks the beginning of the compressed image data stream. | |
| SOF0Start of Frame, Baseline DCT — the most common JPEG compression type. | |
| DRIDefine Restart Interval — written by some cameras (notably Canon) to enable mid-file error recovery. | |
| APP2ICC colour profile or FlashPix extension data. | |
| APP10 | |
| EOIEnd of Image — the 2-byte marker that closes every valid JPEG file. | |
| APP0JFIF application marker — identifies the file as JFIF format and may carry thumbnail and pixel density info. | |
| APP13IPTC data container — used by Photoshop and some cameras for editorial and copyright metadata. | |
| APP14Adobe colour transform marker — stores a byte indicating how YCbCr channels map to RGB during decoding. |
