I want to write a IPTC Tag into an existing tiff file. Do I need to load the image first and then write a new image, or is there a way to read/write a tiff like this: open tiff, change tag, close tiff (-> write/excange tag).

Yes, you can do it that way. But every time after tag update you will need to rewrite the whole directory, so the size of your TIFF file will be increased.

The tiffset utility from the libtiff package does exactly what you need, so you can take it as a sample code.

Regards,
Andrey
