Questions about EXIF data (Windows version)

I'm sending tiff files to GIMP (version 2.6.7 for Windows) from a raw converter. The tiff files contain a lot of EXIF data such as Fnumber, FocalLength, ExposureTime, ISO. and so-on. When I save as jpeg from GIMP, most of the EXIF data is discarded. In the "Save as JPEG" dialog, the checkbox "Save EXIF data" (under Advaned Options" is unchecked. It is grayed out so I cannot check it.

In Chapter 6 of the GIMP manual, it says

Although GIMP uses the “libexif” library to read and write EXIF data, the library is not automatically packaged with GIMP. If GIMP was built with libexif support, then EXIF data is preserved

Here are my questions: (1) Is the Windows version of GIMP packaged with libexif? (2) If not, is there a workaround?

Questions about EXIF data (Windows version)

The Exif data is discarded when opening the TIFF files. So far, only the JPEG plug-in reads and saves Exif data from and to image files.

Here are my questions: (1) Is the Windows version of GIMP packaged with libexif?

Yes.

(2) If not, is there a workaround?

A workaround is to use a different tool - e.g. exiftool - to extract the Exif data from the original files and add it back to the resulting files.

A fix would be to add Exif support to more file format plug-ins (e.g. TIFF, PNG and possibly others).

Regards, Michael

Questions about EXIF data (Windows version)

Thank you, Michael. You solved my problem. I was able to import EXIF data using ExifTool.
