jfgilbert Posted April 28, 2007 Share #1 Posted April 28, 2007 Advertisement (gone after registration) If you wonder how many pictures you have taken with your M8, I think it is available in the exif data. One tag is called "Unique Image ID" and seems to increment by 1 with each picture made. The number I find in mine seems about right for my use, so I believe that it is the picture count. I found this nifty (free) little program to show the exif data (on Mac): http://homepage.mac.com/aozer/EV/ You have to save an image as Jpeg and open it in the viewer. The number is shown as an Hex number, that you can easily convert with the Calculator in programmer mode. Cheers, Jacques Link to post Share on other sites More sharing options...
Advertisement Posted April 28, 2007 Posted April 28, 2007 Hi jfgilbert, Take a look here How many actuations?. I'm sure you'll find what you were looking for!
Shootist Posted April 28, 2007 Share #2 Posted April 28, 2007 My picture/image/file naming count and the unque image ID are about 90 shutter actuations apart. About 3200+ shots for me. Link to post Share on other sites More sharing options...
scott kirkpatrick Posted April 28, 2007 Share #3 Posted April 28, 2007 As long as the unique id is larger than the image count, this makes sense. There might be actions which could increase the shutter actuation count while the image is deleted or aborted (lens cap on). What programs pick this up? I don't see that field in either IrfanView or Capture One. Does Photoshop show it? scott Link to post Share on other sites More sharing options...
scho Posted April 28, 2007 Share #4 Posted April 28, 2007 Reveal is another little Mac app that will read the exif directly from M8 DNG files. It also reports actuations in the same way. Example from last image I shot with my M8: Exif.Photo.ImageUniqueID = 0000000000000000000000000000036d This translates to 877 actuations. The actual image file number was 726 implying that there were 151 actuations prior to the current, continuous numbering sequence. Link to post Share on other sites More sharing options...

Does Photoshop show it? scott Photoshop or Lightroom do not show it. I have only seen it in programs that just dump the exif data, like the exif viewer from the link in the post.

In Photoshop CS2, look under File->File Info->Advanced->Exif Properties->exif:ImageUniqueID. I'm not sure about other versions. Link to post Share on other sites More sharing options...

It works also directly on DNGs. It's called (no surprise!) ExifTool. Here's the URL http://www.sno.phy.queensu.ca/~phil/exiftool. Being Perl-based, it's multi-platform. I've used it for quite some time on many types of images, and it has never caused any problems to me. Cheers, Luca Link to post Share on other sites More sharing options...
Shootist Posted April 28, 2007 Share #8 Posted April 28, 2007 It shows in Bridge, CS2 or CS3. It's actually called Image Unique ID. You have to put the last 4 or 5 character into a scientific calculator using HEX then convert to Dec. Link to post Share on other sites More sharing options...
jfgilbert Posted April 28, 2007 Author Share #9 Posted April 28, 2007 You are right, I only looked at the exif in the info panes, never explored these menus in CS2 or 3. Thank you, Jacques Link to post Share on other sites More sharing options...

But I found my 'Unique Image ID" has been reset either by the new firmware or by Solms when it went in for the hardware upgrade? Does anyone know if the new firmware resets this number?

Alan It doesn't get reset with firmware updates and to my knowledge the image Unique ID never gets reset. I once reset my M8 so it started counting images from 1 again and the IUID still reads the total amount of shutter actuations. I've also upgradeed/updated firmware from 1.09 to 1.091 then back to 1.09 then up to 1.092 and now have 1.102. IUID is still showing total SA.

I had over 5000 images taken before sending it back to Solms for update and repair of sudden death. I was told the camera was working perfectly when they received it. Maybe they changed some other guts of the camera causing the reset. Alan Link to post Share on other sites More sharing options...
