How it works
Nikon cameras store extensive makernote metadata covering vibration reduction status, active D-Lighting settings, focus area mode, flash compensation, high ISO noise reduction, and a shutter count. This tool reads the count Nikon writes as ShutterCount (tag 0x00A7) from a NEF raw or an untouched JPEG; for the standard EXIF fields of the same file, use the EXIF Checker.
