Please, do not auto write "IPTC:ImageType" from tagsFromFile.

Workaround:
exiftool.exe -v2 -m -tagsFromFile "SOURCE.XMP" -MetadataDate=now -ImageType= -o "TARGET.JPG" "SOURCE.JPG"

The only solution to this would be to make IPTC:ImageType unsafe.  But this would cause a problem for someone who wants to copy all of the IPTC.  I think a work-around like yours may be the best solution.

Thanks for your answer...

But there is no IPTC tags, either in XMP or JPEG. This tag creates Exiftool automatically.

Exiftool recognizes the type of -tagsFromFile (XMP, TIFF, ... ) and generates IPTC:ImageType, even if it is never declared.

[Phil Harvey]

This tag must exist in the -tagsFromFile file or ExifTool wouldn't write it.  Since it can't write EXIF:ImageType, ExifTool tries IPTC:ImageType next since you didn't specify a destination group for the copy.

ExifTool tries IPTC:ImageType next

Sorry for being ot, but what exactly is IPTC:ImageType anyway? The exiftool spec doesn't say anything other than string[2], and exiv2 isn't much more helpful as in "Indicates the color components of an image" (http://exiv2.org/iptc.html)

since you didn't specify a destination group for the copy.

To the op: To prevent something like unintentional tag mixing, I find it most useful to explicitly specify the exact tag location everywhere, even if it seems a bit over the top at first and adds some more text to the command line.

The ExifTool tag name documentation links to the standards document which provides all of the available details about these tags.
