I want to access custom TIFF tags

I am interested in reading and writing custom tags in TIFF files using MATLAB. It appears, from a cursory review of the LibTiff website, that invoking tiffmergefieldinfo with a list of the custom tags I need to work with might be enough. But the call is not supported in the tiff object.
I would prefer to not maintain a custom build of the LibTiff library, although that would probably work.
Has anyone worked in this area already?

Mark, would the output of imfinfo be of any use? I think it reads custom tags (as 'unknown' tags in the output).

Mark, if they are numerical values or have fixed length, you could attempt to use the offset field of the unknown tag to gain raw-access to the location of the value in the file (fopen,fseek, fwrite, fclose). Of course, I am sure you are aware of the risks of doing so :)
