Don't know - you'd have to look at the source to figure that out or ask
on gimp-developer.

I wasn't that impressed with the TIFF file plugin though I use it to
save lossless screenshots for articles.  If you are worried it doesn't
read the exif data you can try converting to JPEG first using
ImageMagick and then loading it that way.  I believe the JPEG plugin
supports the EXIF data.  Again, since I don't use EXIF much I'm not
positive of any of this.  You simply have to try it and find out.
