Using -tagsfromfile to copy tags from an xmp file to an image, it copied some of the tags, but not all of them.

I'm using exiftool 8.03.

This is the args file I'm using:

Code:

F:\Pictures\Walks etc\Shropshire Holiday Jul 09\09-07-13\The Long Mynd\Heather _DSC3926a rectilinear.jpg

This is what I get in the commandline when running it:

Code:

E:\Useful progs etc\Image\Image-ExifTool-8.03>exiftool.pl -@ "C:\Users\Rusty\Desktop\args.txt"
Warning: No value for time shift of XMP-exif:DateTimeOriginal
Warning: No value for time shift of XMP-exif:DateTimeDigitized
Warning: No value for time shift of XMP-exif:GPSDateTime
Warning: No value for time shift of XMP-xmp:ModifyDate
Warning: No value for time shift of XMP-xmp:CreateDate
    1 image files updated

But when I check the XMP of the updated file, it contains exif:GPSMapDatum and exif:GPSTimeStamp but not exif:GPSLatitude or exif:GPSLongitude, even though they are all in the source file being copied from, and don't exist in the original file being copied to.

The original XMP of the file being updated looks like this

The XMP of the file being copied from looks like this

The XMP of the file after being updated looks like this

Any ideas?

Thanks,

Dave

Hi Dave,

Sometimes the -v2 option is helpful in figuring out
these problems.  In this output, I can see exactly what gets
written and what gets deleted:

Code:

   + XMP-exif:ApertureValue = '6/1'
    - XMP-xmp:CreateDate = '2010-01-02T22:07:17Z'
    + XMP-xmp:CreateDate = '2009-07-13T09:37:13.26+01:00'
    + XMP-exif:DateTimeDigitized = '2009-07-13T09:37:13.26+01:00'
    + XMP-exif:DateTimeOriginal = '2009-07-13T09:37:13.26+01:00'
    + XMP-exif:ExposureCompensation = '0/1'
    + XMP-exif:ExposureMode = '0'
    + XMP-exif:ExposureProgram = '3'
    + XMP-exif:ExposureTime = '1/100'
    + XMP-exif:FNumber = '8/1'
    + XMP-exif:FileSource = '3'
    + XMP-exif:FlashFired = 'False'
    + XMP-exif:FlashFunction = 'False'
    + XMP-exif:FlashMode = '0'
    + XMP-exif:FlashRedEyeMode = 'False'
    + XMP-exif:FlashReturn = '0'
    + XMP-exif:FocalLength = '10/1'
    + XMP-exif:FocalLengthIn35mmFormat = '15'
    + XMP-exif:GPSDateTime = '2009-07-13T09:37:13Z'
    + XMP-exif:GPSLatitude = '52,33.168200N'
    + XMP-exif:GPSLongitude = '2,51.343500W'
    + XMP-exif:GPSMapDatum = 'WGS 1984'
    + XMP-exif:GainControl = '0'
    + XMP-exif:ISO = '100'
    + XMP-aux:LensInfo = '10/1 17/1 35/10 45/10'
    + XMP-exif:LightSource = '10'
    + XMP-tiff:Make = 'NIKON CORPORATION'
    + XMP-exif:MaxApertureValue = '5357/1482'
    + XMP-exif:MeteringMode = '5'
    + XMP-tiff:Model = 'NIKON D200'
    - XMP-xmp:ModifyDate = '2010-01-02T22:09:06Z'
    + XMP-xmp:ModifyDate = '2010-01-02T22:09:49.26Z'
    + XMP-exif:SceneCaptureType = '0'
    + XMP-exif:SceneType = '1'
    + XMP-exif:SensingMethod = '2'
    + XMP-exif:ShutterSpeedValue = '13301/2002'
    + XMP-exif:SubjectDistanceRange = '0'
    + XMP-exif:WhiteBalance = '1'

As you noticed, the date/time tags are problematic because the "-=" syntax
indicates a time shift for these types of tags, and not a conditional delete
like other tags.  So the existing values are deleted, which isn't what you
wanted.

You mention the GPSLatitude/GPSLongitude are not written, but when I try
this they are (as seen in the output above).

But now that I see what you are trying to do, it is maybe alot easier to do it
like this:

Code:

exiftool -tagsfromfile src.jpg -xmp:all -tagsfromfile @ -xmp:all FILE

This will copy all of the XMP tags from src.jpg then override them with the
ones that already existed in the target image.

Hopefully the command I suggested will work for you and simplify
thing somewhat, but I will improve things in the next release for
this (seldom-used) feature.  As-is it doesn't work
for either shiftable (date/time) tags or tags with value lookups.
