Nikon shutter count: reading NEF and JPEG MakerNotes
Nikon ShutterCount fields are documented in manufacturer metadata, including model-specific ShotInfo blocks. An unedited NEF or camera JPEG is the best starting point, but decoding and interpretation still depend on the model.

Where Nikon stores the counter
ExifTool documents Nikon ShutterCount fields in multiple layouts, including encrypted ShotInfo data. This is why searching the raw file for the text ShutterCount is not a reliable extraction method.

Read an original NEF or JPEG
Save the output with the camera model, tool version, and warnings. Group names help explain multiple counter values instead of flattening them into a single unexplained number.

Check whether the file came directly from the memory card. An exported JPEG may retain exposure settings while losing the proprietary information. If possible, compare the original NEF and the in-camera JPEG from the same capture.
A browser parser may leave MakerNotes undecoded. An absent field in that interface is not a zero count. If a dedicated parser also fails, record the camera, firmware, format, and warnings before asserting a lack of support.
A shutter label does not establish mechanical use
Determine what the specific camera counts, especially when electronic exposure modes are involved. A rising image counter alone cannot establish which physical part moved.
For a useful local check, record a baseline, take a known number of exposures in one mode, then compare the reported values. That experiment describes the tested camera and mode; it should not become a claim about every Nikon model.
Can a file’s counter be changed?
The ExifTool author notes that writable ShutterCount metadata can be changed in a file. This does not establish that the camera’s internal hardware counter was reset. Treat a supplied file as supporting evidence, not a tamper-proof certificate.
