A few days ago, I posted a query about putting my name in the 1DIII as "owner". I was directed to EOS Utility, where I did, indeed, find that I could register my name there. It does NOT, however, keep it "on file" and attach that info when I download it to Zoom Browser and then into Corel's Paint Shop X4, which I use as a processing program. There seems to be no such area to include info in Zoom Browser.
When I open EOS Utility, a click on the "tools" icon opens a small "info" area that allows me to enter my name, among other things. That seems to be as far as I can get.
I may well be missing instructions or a toggle someplace, too.
