Originally posted by tuco I can't help with details of the software on your platform. You should verify the change by having it list the tag's new value out before firing up LR.
So you're using the command line version then? if so I'd think the format would be program name, space, -tag name=, value or "text in quotes", space and finally the file name including the path to it if it's not in the same
directory folder. But I'm assuming exiftool also runs like that on Windows too.
What are the tags you should be using I can't say. That is a confusing area that I've never had to dig in to. Maybe someone else can add to that. But I believe LR will need information about the camera, make, model, lens model and lens identification. The Pentax DNG files I've seen have a
LensID tag. And that tag is populated with matching text from a
Pentax LensType Values list of
Pentax Tags. And in this list of available
EXIF Tags, there is
LensInfo,
LensMake,
LensModel and
Lens tags. I think you could add them all just to make sure but I'd use standard text for any lens descriptions you manually add.
Tuco - thanks.
Can I double check when you say 'so you are using the command line version then' whether this means I'm not using one of the the GUI versions you suggested?
The files I have downloaded from ExifTool are:
ExifTool.exe (application)
ExiftoolGUI (application)
ExifToolGUI (Configuration settings)
ExifToolGUI (Text Document).
If I doubleclick on the ExifToolGUI file (which is the only file with an ExifTool icon) I get the message with a red cross saying GUI Message: ExifTool by Phil Harvey not found. GUI does not work without it - see instructions.Pressing OK to that brings up what I now realise is the Command Line version.
I've read the instructions in the Text Document carefully, and as far as I can tell I've followed them.
I feel like a real numpty with this! I realise I'm taking up quite a bit of yourt time on this and really appreciate it. I will post the problem on the other forum (DP Review) where the ExifTool was suggested in the first place, and see if anyone has any ideas on what i'm doing wrong.
Thanks again.
