Writing new tags to Panasonic files

[mn]

Hello,

I noticed that I cannot add tags to Panasonic RAW files. For example, when I remove all exif data from RAW and then I try to add some random tags, exiftool doesn't write anything. Is this a limitation of exiftool?

Code Select Expand


$ exiftool -P "-IFD0:ModifyDate=2009:02:15 15:25:21" -IFD0:HostComputer=hrusticka -n -X -v Panasonic.RAW
======== Panasonic.RAW

First, I wouldn't recommend deleting all EXIF from any RAW image because many manufacturers store important white balance information in this section.

But to answer your question, only certain tags may be written into IFD0 of Panasonic RAW images.  See the Panasonic Raw tags documentation for details.
