More information on EXIF issues

EXIF data doesn't seem to show up for any of my pictures uploaded with the new mass uploader. -eiriandiffaith [18.06.07, 8:09 am]

• Update: EXIF data shows up for those pictures which have been taken by a particular Olympus camera and whose orientation I've changed in the default microsoft picture viewer; not for anything else. --eiriandiffaith (6/25/07)

After hours of testing (literally) I managed to identify a set of EXIF metadata fields which prevent the Camera and Colorspace Information to show up after upload. Byte order is not influencing this behaviour as far as I know. Here is the list of all data fields I identified:

• EXIF:MaxApertureValue
• EXIF:FocalLength
• EXIF:ExifImageWidth
• EXIF:ExifImageLength
• EXIF:InteropIndex
• EXIF:InteropVersion
• EXIF:FileSource
• EXIF:FocalPlaneXResolution
• EXIF:FocalPlaneYResolution
• EXIF:GPSVersionID
• EXIF:GPSLatitudeRef
• EXIF:GPSLatitude
• EXIF:GPSLongitudeRef
• EXIF:GPSLongitude
• EXIF:GPSAltitudeRef
• EXIF:GPSAltitude
• EXIF:GPSMeasureMode
• EXIF:GPSMapDatum

It's especially annoying that GPS information is disabling camera information processing although GPS data is processed correctly. So you have to choose which is of more importance to you.

The cameras mentioned earlier in this thread (e. g. D70) do have EXIF:FocalLength data in their photos which gets processed. I don't have any explanation for this yet. So there might be a way to include these information, too. Any ideas are welcome.

A proof of concept can be found here. I deleted all aforementioned metadata fields and added GPS information as a "geo:loc=" Zooomr label after uploading (see any Geo Location for syntax example and don't forget the double qoutes & the space between the coordinates).

I have not retested these issues as of 2008-01-09. -Overkill [2008-01-09 21:46 GMT+1]

This is good stuff guys!

EXIF data doesn't show up from the Canon 30D - it does contain the FocalLength? field:

Exif comment    :

I would very strongly suggest bumping the priority on this one up - EXIF data is a very big point (make or break even) for many serious photographers, including myself. I like Zooomr, but if something as basic and essential to digital photography as EXIF data isn't taken seriously, I'll have no choice but to find another alternative.

I just found that if I upload the images without any ITPC data, zooomr can
read the EXIF data just fine.  Once I add any ITPC data, however, zooomr
chokes and can't pull out the EXIF data anymore.  I can still see the EXIF
data using exiv2 without a problem.  I can also see the EXIF data in the
full-sized image downloaded from zooomr.

I made a mistake in the listing of metadata fields above: There is no field called EXIF:ExifImageLength! Instead it should read EXIF:ExifImageHeight. Please keep that in mind if you're fixing this bug, Mr Tate. :)

To everyone else: Currently I'm using the great ExifTool by Phil Harvey to strip the photo of the evil metadata fields mentioned above. Running ExifTool? with the following command will produce a SECOND JPEG file (so your original file shouldn't be touched – though I won't be making any promises here ;) without those fields:

exiftool.exe -o "%f_zooomr.%e" -EXIF:MaxApertureValue= -EXIF:FocalLength= -EXIF:ExifImageWidth= -EXIF:ExifImageHeight= -EXIF:InteropIndex= -EXIF:InteropVersion= -EXIF:FileSource= -EXIF:FocalPlaneXResolution= -EXIF:FocalPlaneYResolution= -EXIF:GPSVersionID= -EXIF:GPSLatitudeRef= -EXIF:GPSLatitude= -EXIF:GPSLongitudeRef= -EXIF:GPSLongitude= -EXIF:GPSAltitudeRef= -EXIF:GPSAltitude= -EXIF:GPSMeasureMode= -EXIF:GPSMapDatum= photo.jpg

I'm attaching a .BAT file you can use to do the job for you as well. But again: No warranty for nuttin.

Zooomrfy your EXIF tagged photos (requires ExifTool?)

No more EXIF related issues for me in Zooomr 2008. Setting this ticket to user review in case someone else still runs into problems.

I would have to disagree. I still don't have EXIF data on my IPTC tagged photos. I'm re-opening this for now, but let me know if you'd rather me just create a new ticket, as it's not exactly the same problem.

Never mind, ignore that.  It works.  I just hadn't uploaded anything new yet
because of the flash upload bug.
