keep LR edits while using Exiftools to change timestamp

[torge]

Is it possible to keep the edits already made within LR while one batch changes the dates on files?
I haven't been successfull using a command like:

exiftool -AllDates-=1 DIR

The edits that LR stores with the raw files all seem to be gone after I read in the updated exif data.
I am aware that this might be more of a LR problem, but I guess I should ask here first.


Thanks in advance for any help provided,
cheers,
Torge

Hi Torge,

LR writes metadata to sidecar XMP files (unless you are using DNG).  I would suggest updating the XMP files then re-importing the metadata into LR's database (I'm assuming that LR maintains a database of its own, but I don't know how to force it to re-import the metadata from a file).
