Thanks for this info. I understand that these are just warnings. I know that the TIFs are still working in gimp, convert, etc.
But "convert" for example is complaining about tag 34864: convert: Unknown field with tag 34864 (0x8830) encountered. `TIFFReadCustomDirectory' @ warning/tiff.c/TIFFWarnings/861. and this tag is noted as "mandatory": Code Name Short description Source of tag Note 36864 ExifVersion The version of the supported Exif standard. Exif Private IFD Mandatory in the Exif IFD. That brings the question to my mind if the TIFs are compatible with the non-Linux world: Windows, Mac, Photoshop, etc. Do you know?
