I wanted to build an awesome place for people to discuss module specific issues, but I don't have any more time for this, and there are much better places to discuss Perl-related issues. I'd recommend asking your question on Stack Overflow or on Perl Monks.
If you are looking for a Perl tutorial or Perl-related news, I hope these links will serve you well.

Modifying tags in multipage TIFF
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
