Duplicate tags in the same group

[JudyN1]

It looks like my Sony A77 camera outputs two tags for the field DynamicRangeOptimizer. ExifToolGUI diplays both.   One has the contents I want, the other appears to be what the Minolta tags are/were.  They are both in the same group (Sony).  I want to move the information to a field that Lightroom displays, but the one I get is the wrong one.  I have the tag ID, but I don't know how to use that in the command line.  Is there any way I can get the one I want?

Hi,
Yes, from A77 example file I have, there are two DynamicRangeOptimizer tags in Makernote section. One of both is in main Makernote group, and another is in "Copy1" subgroup of Makernote -you can see that by checking menu Expert>Maker: view tags grouped by instance -g4 in GUI.
You can change one of these two tags (so hopefully LR will display what you want), but I'm not sure if that's a good idea. If you're sure LR is showing wrong tag, then LR is having problem.. and hence, LR should adapt. This might (and probably will) happen in future -and then, you'll be forced to modify tags again.

To copy this to another tag, use an argument like this with the "exiftool direct" feature:

"-sometagname<copy1:dynamicrangeoptimizer"

Yes, I need to copy to another tag.  When I said I get the wrong one, I meant with exiftools trying to copy.  When I looked at them I thought they both were Sony "subgroup", so I guess I don't know quite how to look.  I'll try Copy1.  Thanks!

Hi Judy,

There 5 different families of groups used to distinguish tags for various purposes.  To see all groups for each extracted tag, use -G:0:1:2:3:4 on the command line.  See the -g option documentation for details, the Tag Groups section of the exiftool home page, and the GetGroup function documentation in the API reference for more details.
