Nikon D3500 Shutter Count
◐ Expected to work
This camera hasn't been personally tested here yet, but it shares its metadata layout with a sibling model we have confirmed, so it's expected to work the same way.
Shutter count for the Nikon D3500 is read from MakerNote tag 0x00A7 (ShutterCount) in the camera's NEF file metadata — entirely in your browser, the file is never uploaded anywhere.
