I am experiencing an similar issue as reported here
I have a series of scanned tif images that are throwing errors when ever I try to use the identify or convert commands.

Code: Select all

Magick: long_portrait.tif: unknown field with tag 33000 (0x80e8) encountered. `TIFFReadDirectory' @ warning/tiff.c/TIFFWarnings/70
6.

Some times Imagemagick still run the command despite the warnings, but more often than not it stops.
These tif images are also produced on a Kofax scanning station.

Code: Select all

Magick: long_portrait.tif: unknown field with tag 33000 (0x80e8) encountered. `TIFFReadDirectory' @ warning/tiff.c/TIFFWarnin
gs/706.

An example image can be found here:

Your file works fine for me on IM 6.6.9.6 Q16 Mac OSX Tiger

It does take time to convert (especially the first time IM is used after booting), so be patient.

convert long_portrait.tif long_portrait.png
convert: long_portrait.tif: unknown field with tag 33000 (0x80e8) encountered. `TIFFReadDirectory' @ warning/tiff.c/TIFFWarnings/706.

The warnings are just that, warnings, because there is some TIFF information field that IM does not recognize. But that should not affect the conversion. You can stop those by using -quiet

convert -quiet long_portrait.tif long_portrait.png

-quiet did the trick

It turns out that IM was still reporting the results of identify after the warnings:

Code: Select all

>identify -format %[width] long_portrait.tif
Magick: long_portrait.tif: unknown field with tag 33000 (0x80e8) encountered. `TIFFReadDirectory' @ warning/tiff.c/TIFFWarnin
gs/706.
2631

Code: Select all

>identify -quiet -format %[width] long_portrait.tif
2631

Sorry about that.
A bit of a PEBKAC issue on my end.
Thank you for your time
