john_newell Posted July 20, 2011 Share #141 Posted July 20, 2011 Advertisement (gone after registration) I see no actuation data in this file sorry. Try this little app with your original DNG or JPG file. software What a nice little program! I had missed that earlier, I guess. Thanks! Link to post Share on other sites More sharing options...

JHAG Posted November 19, 2011 Share #143 Posted November 19, 2011 If you use firefox as browser, this plugin will do the job nicely:https://addons.mozilla.org/de/firefox/addon/3905 Then look for the unique ID which is at the end of the file and looks like this: Image Unique ID = xxxxxxxxxxxxxxxxx It's a hex code, which you can convert to decimal here: hexadecimal conversion, convert decimal to hexadecimal I never could find it :confused: Attachment below Exif Image Metadata.pdf Link to post Share on other sites More sharing options...
JHAG Posted November 19, 2011 Share #144 Posted November 19, 2011 To me the simplest method : Steps to display shutter actuations of a Leica DNG file: open image file in Preview.app open inspector mark unique image id value (double click on it) copy unique image id value (cmd + c) open calculator.app (just type "1+1" or any other mathematical formula in spotlight and hit "enter") switch view to "programmer" (cmd + 3) paste hexadecimal value from unique image id into the calculator (cmd + p) switch to decimal system (click the "10 button" on the calculator) Link to post Share on other sites More sharing options...

lct Posted November 19, 2011 Share #146 Posted November 19, 2011 Do you mean M8Info? Works fine on my MacBook Air with OSX 10.6.8. Otherwise Photoshop CS3 does work as well (File / File Info / Advanced / Exif Properties / exif:ImageUniqueID). In both cases, as well as with Preview.app, better use an original file though.

lct Posted November 19, 2011 Share #148 Posted November 19, 2011 Yes no problem at all with OSX 10.6.8. Would you have OSX 10.7 (aka "Lion")? Link to post Share on other sites More sharing options...
cbretteville Posted November 19, 2011 Share #149 Posted November 19, 2011 The imageuniqueid is not neccesarily the same as the shutter actuation count. It may look that way for many, but it is not correct if your shutter has been replaced or upgraded. The imageuniqueid was not reset when Leica upgraded my M8 to the quieter M8.2/M9 shutter.

lct Posted November 20, 2011 Share #152 Posted November 20, 2011 Getting the ImageUniqueID is the only way to determine the number of shutter actuations AFAIK. This can be achieved through different softwares like Photoshop, M8Info, Exif Viewer or Preview.app indeed. In your M8Info problem, Lion's compatibility must be the culprit i guess.

ErikP Posted November 24, 2011 Share #153 Posted November 24, 2011 Is there an iPad app that handles shutter count for Leicas DNG files? I was looking in AppStore but could not figure out if there is? Thx Erik Link to post Share on other sites More sharing options...

It getting the ID that is hard. PS has come out with a editing app for android and I think one for IOS is going to follow soon. That might do it.

PS has come out with a editing app for android and I think one for IOS is going to follow soon. That might do it. I go via Leica jpg -> Firefox + plug in -> HEX converter. It would be good to just press one icon on the iPad and select a DNG file. Well hopfully it will show up soon Link to post Share on other sites More sharing options...
cbretteville Posted November 24, 2011 Share #156 Posted November 24, 2011 This is the only way to determine actuation numbers on M8 & M9 AFAIK. There is no data recorded in the image files that is the shutter actuation count. There is probably a counter kept in the camera's non volatile ram. I know I, in 2007, published a paper on the metadata in the M8 image files that asked the question if the counter in the maker notes was the shutter count, but it isn't, it is the same as the ImageUniqueID on the public exif block. Neither number is reset when the shutter is replaced. Combined with the camera's serial number it makes up a unique id for each file that comes out of the cameras. For some cameras it indicates an approximate count, but unless you have the camera's full history you can not say whether the number is correct or not.

I joined him, and he just updated is cool app for Lion. software "Hallo Johan, so, habe jetzt die Zeit gefunden und das Programm angepasst. Eine etwas aktualisierte Version (0.21) ist beigefügt und befindet sich jetzt auch auf meiner Webseite. Sie sollte jetzt auch mit Lion 10.7x funktionieren. Kannst die Info auch gerne weitergeben.

That might do it. #1 iPad App now show the ImageUniqueID - Photogen. #2 There is also an App for HEX conversion - iConvertHDB Very smooth to keep track of shutter count when shopping for a used M body. Ask for a DNG file via mail and run these two apps. Link to post Share on other sites More sharing options...
