File Number tag

[mvadu]

Hi Phil, I am wondering where to get the File Number/Shutter count for Canon DSLR images.

I have a file from Canon T1i, and

Code Select Expand

-all t1i.jpg gives
File Number                     : 100-3706
Whole code branch search revealed only one place in Canon.pm(Image::ExifTool::Canon::FileInfo) which is index one for FileInfo tag.
However

Code Select Expand

-U -v3 t1i.jpg  has only
Canon_FileInfo_0x0001 = 0
- Tag 0x0001 (2 bytes, int16s[1]):
     0e68: 00 00                   

So I am kind of stuck, how to get 100-3706 from 0x0000. 3706 sounds to be correct value of shutter count for my camera though. Can you please guide me to the tag from where you derive this value?

I think you are confused.  In this case, FileNumber is a Composite tag which is derived from FileIndex and DirectoryIndex.

Hi,

Not sure if this is the right place to ask this, but it is related to the File Number tag. I would like to rename some files using this tag, as I renamed them ages ago but would like to rename them back. I am sure this would be possible with Exiftool, but I am a little overwhelmed by the options!

Is this possible to do ?

Thanks for your help,
