If you want metadata to be preserved - put it in a documented metadata format: EXIF (but only documented tags), IPTC, or XMP.

Photoshop throws away undocumented tags for a reason: they cause big problems when they get out of sync with the image data. (think: smoking printer -- yeah, it really happened)

I had similar needs, and have written an enhancement for the tiffset utility that allows you to do this. I have uploaded the corresponding patch to bugzilla. You should be able to download it from there if desired and rebuild tiffset. Hopefully this will soon be included in a standard logTIFF release.

Subject: [Tiff] Writing custom TIFF tags to Photoshop saving TIFFs (withPhotoshop)

Hi -

I'm thinking of introducing custom TIFF tags into my TIFF images produced within Photoshop, and I'd like Photoshop to save the TIFF images *with* the custom TIFF tags.

Would someone please give me pointers (i.e. general direction) on how I would go about doing this?
