What is a .jpg file?
JPG is the common extension for JPEG, a lossy raster format that uses discrete cosine transform compression tuned for photographic images. It is 8-bit truecolor with no alpha channel, and quality is traded against file size via a compression factor. It is ubiquitous for photos on the web and from cameras.
How to use this file
Use an example JPG to test decoders, EXIF/metadata parsers, re-encoding quality, and orientation handling, or to confirm converters and image pipelines process baseline and progressive scans correctly.
How to use this file for testing
“EXIF Orientation — Rotate 180 (tag 3)” is a deterministic Novus Examples fixture for ICC / colour profile, Conversion testing. Orientation ladders, SAMPLE GPS EXIF, and sRGB vs Adobe RGB tagged images for colour-managed pipelines and EXIF readers.
Documented properties for this file: 288×288 · seed 1303. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.
Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.
For image AI or enhancement tools, run the model or filter on this file and diff against the clean or ground-truth companion in the same group when available. Keep seeds and documented damage parameters in your evaluation notes so regressions are attributable.
Compare tagged vs untagged or orientation-tagged twins. Confirm your colour-management or EXIF-Orientation path honours the documented profile/tag rather than assuming sRGB upright pixels.
