If the "Electronic Front-Curtain Shutter" (EFCS) is set to OFF (which seems to be the default for the A77MII), the shutter will fire twice for each picture. Besides white-balance bracketing, as Phil mentioned correctly, HDR or panoramas, there is another reason for the camera to count the shutter twice: Analyzing my photos made by both cameras, I realized the A77M2 always counted at least double the number of actual images made. In spite of the fact that it took me some time to solve the issue, I agree 'ShutterCount' makes more sense! Suddenly, my program would report 0, so I tried debug without success, until I learned changed the name of the tag to 'ShutterCount' in Version 11.25(?). Not until recently, I found out some Sony cameras log the shutter count to the maker notes for my SLT A55V and ILCA-A77MII and ExifTool reports it as 'ImageCount'. I am left to wonder how people selling A7RIIs on Ebay are able to post a shutter count number. This is pretty strong indication that "image count" is at least something that increments with every exposure. Taking a look at the pictures in question, 387-389 are indeed the same building in a city, and then a change of scene to greenery coincides with 416.

Some minor detective work:Ĭhecking StarGeek's page to get Sony ARW files, I took four, & can see the page gives files that have a numerical order: Similar for -ImageCount tag if you wanted that as well. To get just the shutter count, if it exists, add -ShutterCount to the command. What is the (or is there a) rename convention for Exiftool to limit itself to outputting the shutter count (or whatever "shutter count" is called)? Or maybe not, the file I grabbed had ImageCount of 4214 and ShutterCount of 5812. It's also worth noting that there is also an ImageCount tag for some cameras, so that might be useful to extract as well. Also, as mentioned on that list, ShutterCount is "only valid for some DSLR models". This list is not necessarily everything that's in the file, just what Phil has decoded, and is subject to change at the whim of Sony. You can also find a list of Sony Makernotes tags that exiftool can recognize here. It looks like in the file I grabbed that the tag was simply named ShutterCount. I grabbed a random Sony ARW file from and ran exiftool -*shutter* -g1 -a -s on it (yes, you can use wildcards in tag names). In that long list of data, what is "shutter count" called for an ARW (Sony RAW) file? 1.Quote from: beachcolonist on January 15, 2017, 05:08:39 PMġ.So I want to get shutter counts from Sony ARW files and other image files.
