I apologize if this request is off topic (not directly related to GIS), but it's the first forum I have found that discusses developing topics for the TIFF format.

You are posting to the right place. Unfortunately, the issue you describe is a long-standing weakness with libtiff and there are plenty of people waiting to learn how to do exactly what you describe.

Bob

I use libtiff for saving high dynamic range images, and I need to write EXIF data into the TIFF files.

I need to create a specific IFD for EXIF, but I cannot find any example anywhere. I also cannot find any documentation to use the TiffCreateDirectory function.

Please does anybody have some information about this?

Thanks in advance
Axel
