Image Serial Number

[ssim]

I was always under the impression that a unique serial number was applied to each image. This was constant no matter what you may have renamed your images basic file name to.

I was doing some hunting today as I needed to access this given a slip up in copying and renaming files as they were copied from a portable drive to my main computer. We're talking about RAW files, btw.

My 1DsMKIII and 1DMKIII don't show a serial number for the image, they show a serial number for the body only. I went back and looked at the CR2 files from my 1DsMKII and the ones that I looked at did not have this serial number but the ones from my 1DMKII did. Heck even my little G9 assigns a serial number to the image.

I've gone through the manual for the 1DsMKIII and can't find anything that references this. I have also done a search of the Canon knowledge base and can not seem to locate the answer to this. Did Canon abandon this in later models of the 1 series. I am hoping that perhaps someone can shed some light on this for me.

Thanks

Hi, Sheldon,

I don't know anything about 1-series EOS cameras, but in the 20D etc. the name "image serial number" is sometimes used to mean the number that is a combination of the numeric part of the folder name and the numeric part of the file name. For example, in a 20D, this file:

457CANON\IMG_5710.JPG

has "image serial number":

457-5710

It is always derived from the folder name and file name given the image in the camera at the time it is taken.

If that is reset, then the image serial numbers will no longer be unique.

I have never heard of a "permanent" serial number series for EOS cameras that advances inexorably.

Hi Sheldon
I too have a EOS 1D3 & when I look at the meta data shown in Capture One under the file info the "Image Serial Number" row is blank. However in the row "Settings File" the following is shown for 3 consequtive images taken a minute apart of the same scene with all the same camera settings.

UID19A508FD63D2D12FE9A1D1702E9606CE.C1w
UIDD0CD08ED5D93C09DB74149B2377DC573.C1w
UID843859D319FE4CB5235248B841022569.C1w

The fact that there's a .C1w at the end may mean that it's capture one that's putting this data there.

Not that this helps much. Sorry.

Cheers
Ross

It's not a cost-free solution, but if you use BreezeBrowser Pro you can configure the program to rename the file on download with the shutter count number which would be unique.

If I read the instructions correctly a unique camera number is assigned to the prefix of each image. Mine is _K1T. There is an option to change it in the menu.
