Hi Phil,
I have a TIFF, containing several pages, where each page has its own IFD entry, e.g. IFD0+IFD1...IFD4. Now, each of IFD contains the same tags (among others): Software, ModifyDate, DocumentName,...
It's easy to modify any tag if IFD is specified... Question:
How do I edit/delete tag in all existing IFDs at once? You know, something like
exiftool -IFDall:DocumentName=Fish image.tif
Another question: In latest version history (v7.98) you wrote, you've changed one Canon tag name. Where can I see which one? Is there any "changing tag names history"? I ask, because my GUI depends on your tag names.
Thanks for answering,
Bogdan

Hi Bogdan,
Unfortunately there is no way to easily delete something from
all IFD's. You must specify each IFD individually. This has come
up in the past, but I can't think of an easy way around it.
Sorry for being a bit obscure in the exiftool revision history.
I changed "NoiseReduction" to "LongExposureNoiseReduction2".
I use the -list option myself to review all tag name
changes for each release, perhaps this would be useful for you
too. I just do a "diff" with the tag list from the previous release.
- Phil

Hi Phil,
Ok, I can understand about multiple IFD's. I've just thought there's some "secret way" -it happened before you've surprised me :-)
Thank you for telling me about Canon tag -even there are very few tags GUI is allowed to modify, though.
Wish you the best,
Bogdan
