gqview is Fedora Extras, not Core.  Re-assigning.
Comment 2 Michael Schwendt 2006-03-16 19:46:50 EST
Can you provide a test file? EXIF information within a digicam
picture is displayed fine here.

Comment 4 Michael Schwendt 2006-03-17 06:14:19 EST
I see no such EXIF ISO speed rating tag (0x8827) in your file and not
with a hexdump either, whereas other files taken with other cameras
contain it.

I'll check if it is a camera problem this week.

No EXIF in this one either

Straight from the D50.

The EXIF data isn't stored in the standard location.

Read about it here:

> The EXIF data isn't stored in the standard location.

That's also what the thread said you linked to originally. Quote:

    Nikon hides the ISO setting in the EXIF "MakerNotes" field.

If you believe the developers of GQview should hack such a proprietary
extension into their EXIF support, get in contact with them:

I logged it as a request on gqviews' sourceforge project request page.
