EXIF data explained: what every photographer should know
Every photo you take carries a hidden layer of information: the date, the camera, the lens, the aperture, the shutter speed, the ISO. This is EXIF data — and it's the foundation of automatic photo sorting, culling, and search.
What is EXIF data?
EXIF stands for Exchangeable Image File Format. It is a block of metadata that your camera writes into every file at the moment you press the shutter. The data rides along inside the JPEG, RAW, or HEIC file and can be read by any capable photo tool.
EXIF typically records the date and time, the camera make and model, the lens, the aperture, shutter speed, ISO, focal length, GPS coordinates, and the image orientation — everything you need to understand how a photo was taken without guessing.
The most useful EXIF fields for photographers
| Field | Example | Use |
|---|---|---|
| DateTimeOriginal | 2025-06-15 14:23:11 | Sorting by date |
| Make | Canon | Camera manufacturer |
| Model | EOS R5 | Camera model |
| LensModel | RF 85mm F1.2 | Lens |
| FNumber | f/1.8 | Aperture |
| ExposureTime | 1/500 | Shutter speed |
| ISO | 400 | Light sensitivity |
| FocalLength | 85mm | Focal length |
| GPSLatitude/Longitude | 48.1351, 11.5820 | Capture location |
How automatic sorting uses EXIF
Photography Workbench reads EXIF to build a folder structure automatically. A shoot is organised into a hierarchy of year, date, camera, and file type:
2025/
2025-06-15/
Canon_EOS_R5/
RAW/
JPEG/Pair detection keeps RAW and JPEG files with the same filename together, and Smart Folders cluster bursts into events based on the timestamps between shots. The result is a library you can navigate by date and camera instead of a flat pile of files.
Why some photos have no EXIF
Screenshots have no camera model to record. Edited images often lose their metadata when they are re-exported by software that strips it. And social networks — WhatsApp, Instagram, and others — routinely remove EXIF before serving an image back to you. If a photo came from one of these paths, its EXIF is likely gone.
How to fix missing EXIF
- Use the EXIF editor in Photography Workbench to set the correct date and camera.
- Run GPS mass correction by importing a GPX track from your camera or phone.
- Set the date and camera manually for individual files.
FAQ
Is EXIF data private?
EXIF often contains GPS coordinates, so remove it before sharing photos publicly.
Do RAW files have EXIF?
Yes, and RAW files often carry more metadata than JPEGs.
Can I sort by lens?
Yes, Photography Workbench reads the lens model and can use it for sorting.
What if EXIF is wrong?
Use the EXIF editor built into Photography Workbench to correct dates and camera info.
Let your metadata do the sorting for you.
