Hello,
I have a problem when saving for the web a jpg file in Photoshop (CS6 or CC does the same). Of course, the option of conserving all metadata is activated.
My problem is that some metadata are not affected to a TagID. I've verified this running EXIFTool, in attachment is a caption of the result for such a file.

As you can see, some exif infos are affected with the right TagID and Tag name (such as 0110 model for the Canon EOS 5D Mark III), but for some other, the TagID isn't showed : ??-lens : EF 70-200 f4L IS USM. In this line, "??-" would be "a434", according to the TagID tables.
The fact EXIFTool or photoshop clearly associate the good info to the good Tag name (EF 70-200 f4L IS USM for lens in my exemple), mind me the tagID is somewhere... I need this tagID in a program, but I see no way to find it.
If someone have an idea?
Thank you by advance
Try adding -a to your command, maybe -g1 as well.
Some tags can be duplicated in other places and ExifTool won't normally list them all. The -a option will show the duplicated tags. Adding the -g1 option will let you know what metadata block those items fall under. I'm guessing that the tags you're looking for are being duplicated as Composite tags.
Thank you StarGeek.
I've used the -g1 option and it shows me that Lens is a tag under the XMP aux block. So I can't address this tag in my program. The only way I found is to copy the info of this tag to the LensModel tag I can adress... Not the best way, but it works...
Thanks again.
