How it works
Some manufacturers write the number of releases so far into the manufacturer data (MakerNote) of every photo file. The tool reads only this small area at the start of the file, even for RAW files of more than 50 MB, and shows the value. It uses the tag descriptions of ExifTool for this. The counter belongs to the photo and applies to the time it was taken, so a newer photo gives a more recent value than an old one.
Which file to use
The best choice is an unedited file straight from the memory card, as JPEG or RAW. Programs and services that save an image again or shrink it often drop the manufacturer data; this applies to messengers and social networks. On mobile devices the photos app can convert a file when it is chosen. In that case choose the file straight from the memory card or from the file manager.
Supported cameras
Supported are models that were checked with real test files. For other models of the same brand the tool shows a value it finds, with a note that the model has not been checked.
| Brand | What is counted | Files | Checked models |
|---|---|---|---|
| Nikon | Total number of releases. Newer models also report the releases of the mechanical shutter separately. | Files:NEF, DNG, JPEG | Show 73 models
|
| Fujifilm | Images taken (image counter). The value can reset after a firmware update. | Files:RAF, JPEG | Show 32 models
|
| Pentax / Ricoh | Releases of the shutter, without live view and video. After servicing the value may be reset. | Files:PEF, DNG, JPEG | Show 37 models
|
| Canon | Only a few models write a counter into the file: EOS-1D, EOS-1D Mark II N, EOS-1D Mark III, EOS-1Ds, EOS R6 Mark III. On the EOS R6 Mark III it counts the images on the card and starts again after formatting. | Files:CR2, CR3, TIF | Show 5 models

Cameras without a counter in the file
According to the ExifTool documentation, photo files from Panasonic, OM System (Olympus), Leica, Sigma and Hasselblad carry no shutter counter. Most Canon models do not store a counter in RAW files either: the checked files of the EOS R, R3, R5, R6, R7, R8, R10 and 5D Mark IV contain none. Sony files do contain a counter, which is not evaluated here yet. Where a photo holds no counter, it cannot be determined from a photo file.
Frequently asked questions
Is the photo uploaded?
No. The file is read in the browser, nothing is sent to a server and nothing is stored. Once loaded, the page also works without a connection.
What does the value count on Nikon cameras?
On Nikon cameras the file holds the total number of releases, so mechanical and electronic ones together on models with an electronic shutter. Newer models also report the mechanical releases separately, which the tool shows as its own line.
Why does the counter reset on Fujifilm cameras?
The Fujifilm value counts images taken. The ExifTool documentation notes that it can reset to 0 when new firmware is installed. A low value therefore does not prove that the camera was used little.
What does the counter count on Pentax cameras?
The counter covers releases of the shutter, also without a stored image, but not live view and video. According to the ExifTool documentation, servicing can reset the value.
Can the value have been changed?
The value is stored in the metadata of the file, and metadata can be changed. It is therefore a guide, not proof. An old photo also shows only the state when it was taken.
Why does the tool show no value for my camera?
Either the camera writes no counter into the file, or the manufacturer data is missing, for example because the photo was edited or sent through a messenger. The section on cameras without a counter names the brands whose files hold none. For a model with a counter, the unedited original from the memory card helps.
