Which exif attribute contains the shutter actuation count?


Recommended Posts

Yes you need to look at a file straight out of the camera and you need an Exif Viewer that shows the Fujifilm specific fields.

Most of these fields (including the shutter count) are not documented by Fujifilm and not displayed by viewers that only show basic EXIF.

Unless you are going to actually parse up the binary file you are going to trust a viewer of some sort.

If you want to look at the raw exif data without uploading your file to a remote web site you can use this:

Fujifilm Exif Viewer

If you click on the plus sign top left you can load an image file into your browser (jpg or raw).

The default view shows you the image and interpreted metadata - but if you right click and choose the EXIF option it shows you the entire list of EXIF tags - including Fujifilm specific - and the raw data without decoding.

Scroll down and look at tag 1438 which is the field normally interpreted as shutter (or image) count.

I've always been curious about this shutter count issue, and why it's more difficult on a Fujifilm. Sincere thanks to all three of you for divulging this top secret information, and sharing the availability of web-based tools to do this, and especially Greybeard for his app, which displays information in such a well organized fashion. Clearly a standout feature.

I use five or six graphics programs with exif capabilities, and none of them display shutter count. In fact, all of them display the exif data in formats different from one another. 

After spending a couple hours researching exif protocol, I discovered most of us already have a tool right at our fingertips that displays information nearly as nice as Greybeard's web-based tool. https://exiftool.org/ is open-source, and runs on Windows, Mac, and Linux.

So I started out the night with no clue how to find shutter count, and ended the night with the tough choice of which excellent tool to use to find it. 

Thanks again guys. 😀

I’m a big fan of Exiftool and have used it extensively. It has one (smallish) problem with Shutter Count (or Image Count as Exiftool calls it) - it only uses part of the field and will roll over when it gets to 32K - whereas the actual field used by FujiFilm is capable of holding 64K (and then rolls over back to the start)

Yes, I was just looking further at your web app, and saw you use Exiftool as its engine. Clearly your web app is the best tool, IMHO, because of the structure in which you display the information. Thank you for making it available to us.

There is one thing I have never gotten clear in my mind about Fujifilm using the term Image Count. I am not sure if that includes images gotten with only the mechanical shutter or if it includes ones obtained with the electronic shutter. I suppose it is easy to fire off several shots with only the ms engaged, several with only es engaged, and then some more with ms + es engaged and check the counts to see. Maybe some day down the road when I get really curious.

When researching this last night, I came across multiple references that said the image count includes both mechanical and electronic shutter actuation, and this was a Fujifilm idiosyncrasy. I recall none saying it was mechanical only.

Yes it includes both MS and ES - and to make it worse - on recent cameras it includes images taken with pre-shot that might not even get written to the card - its not a good guide as to the life of the mechanical shutter.

FujiFilm doesn't call it Image Count - they don't call it anything at all as they don't document their EXIF fields - the Exiftool developer - Phil Harvey - came up with that name.

Hi, I just tried your app with a RAF file to know the number of actuations done by a GFX 50R. If I look in the metadata tab it says

Shutter Count 1797


But if I right click to get the EXIF tab and look at #1438 tag I find : 34565 (Image Count)
Which one is the good one ?

That does work for my XT3 but unfortunately the shutter count doesn't appear for the XT100?

The Shutter Count tag used by the online viewers doesn't exist in files from the X-T100 and X-T200 - I don't know of any way of getting shutter count from those cameras.

    • I wish I could help. I have read the charts on what these settings save and what it doesn’t....have never been 100% comfortable using.  But never had that particular issue.
    • I setup my C1 for bird and action settings. ISO3 (shutter 2000, 125-6400ISO, AF zone, bird). If I'm on a single ISO setting and select C1 it will not go to the AUTO3 setting. If I'm currently on auto iso1 or iso2 it will go to iso3 but the top iso value displays as 1600 even though I set it to 6400 max)? I basically still need to go in and manually change to auto3 to get it to work. Any thoughts would be appreciated.
    • LCD Problem on my X-H2. Camera is 3 months old.  Just this week, LCD was not going on, or it was on then went off, while opening it and turning it outward. Eventually it would come back on after a minute or two. Doesn't happen all the time, but did happen a few times while hiking in cool weather. Has anyone else experienced this yet? I have the settings so that the LCD goes off when I'm using the EVF and I know where that sensor is, so its not user error. I know there have been issues with Fujifilm LCDs in the past, so I'm concerned that this will get worse and I'll have to give it up for a month while its repaired. I'm still within the Amazon return window so considering sending it back for a replacement. All comments and suggestions are welcome and thanks!

    • There are several ways to fix that. Try this, go to System Preferences, click Security & Privacy, then select the Privacy tab. Scroll down and click Full Disk Access. There should be a little + symbol somewhere, click on it and you should be given a dialog box to find the app you want to add. Select it. Now, along the way you will have to enter your password (assuming you have permission to add / delete applications, etc.) to give permission for these thing to happen. An easier way is to delete the app, empty the trash, restart the machine, and reinstall the application, only this time give it the needed permissions as you are going. As far as the tiff files go, it depends on the converter you are using. If they export in 16 bit tiff format, (do not use eight bit) you should have the data but when you open it in your editor, it will have the selected profiles applied as a starting point. ie your white balance, film simulation, etc. etc. because that information is embedded in the tiff from the raf, and used by the editor as a starting point to display the image. Some manufacturers' raw files are actually tiff files with a little proprietary info added in, I have read that Adobe's DNG format is just that as well, a tiff file with a few other things tossed in for good measure. Fujjifilm is now using tiff as a storage option along with .jpg and .raf in their latest camera releases. It is a good format.
