If Canon can tell us from just a file, then it has to be in the EXIF somewhere, but I have never heard of this.

I have heard it, or rather read it here and there, which may be why I now question everything twice.

Oh, wait, that's cause of GWB.

Let's hope your digging proves this theory wrong!

If no one has found it yet in the EXIF, or the hex data, and Canon has to have the camera in hand to check the shutter counts, then I am thinking it's a likely scenario. :(

We just need some enterprising network person to write a ping program to the camera when it is hooked up to see what commands could be issued. Basically reverse engineer the EOS utility, because that can write out the owner name, etc to the camera, and the shutter count would most likely be stored in memory very similiar to the owner name, etc. There are probably getter/setter methods that can be invoked to retrieve alot of this "technician data".

This is how all the automotive OBDII performance tools were created, like ls1edit, etc, where you can change fuel maps, timing tables, etc in your vehicle's computer, people wrote programs that listened in on the info bus and figured out the command structure.

I've said it before. Someone should be able to write some new firmware for these cameras. I've heard it was done for the 20D but forgot the details. Must not be a market for it, or it would have been done. :)

According to this site: http://gphoto.org/proj​/libgphoto2/support.ph​p (external link)
gphoto2 supports the 1D3 "In PTP mode"
Has this ever been tried? I skimmed this thread and I could not find any mention of gphoto2. Here are the step-by-step instructions:
https://photography-on-the.net …/showthread.php​?t=1058019


Canon EOS 7D | EF-S 17-55mm f/2.8 IS USM | EF-S 55-250mm f/4.0-5.6 IS |
EF 100-400mm f/4.5-5.6L IS USM | 250D | EF-S 10-22 mm f/3.5-4.5 USM | 580 EX II |
