Shutter Count
Inspect an original camera file. A missing or unsupported count stays unknown.
WORKSPACECheck what a file can prove. Some cameras write a shutter or actuation counter into maker notes. Others do not, and an ordinary image number is not automatically that counter.
Before you start: Use an original camera file if available. You do not need to know the counter tag in advance; the result identifies what was found.
- Actuation counter
- A camera-recorded count of a particular type of operation. Its meaning depends on the model and field.
- Maker notes
- Manufacturer-specific information stored in some image files.
Start here — Use an untouched file: Choose an original file from the camera. A downloaded social image or edited export is less likely to retain maker notes.
What you should get: Either a supported counter with a stated interpretation or an explicit cannot-determine result.
Full steps, example and limits
- Use an untouched file
Choose an original file from the camera. A downloaded social image or edited export is less likely to retain maker notes.
- Read the field and model
Look at the reported source tag, camera identification and interpretation, not only the number.
- Keep uncertainty
If no supported counter survives, the result should say so. Try another original from the same body rather than estimating from the filename.
Try this: Inspect two consecutive originals if you have them. Compare the source tag and its value; do not assume electronic and mechanical exposures share one counter.
Know the limit: This does not predict remaining camera life or certify a seller’s claim. Model support and retained metadata limit the result.
