AttilaHan Apr 1, 2013 10:08 AM (in response to Lee Jay)I mean ... if we check the "write date or time changes to into proprietary raw files" checkbox in catalog settings, why does Lightroom creates sidecar .xmp file? Does it not write to original raw file?

3. Re: Changing date/time ...
Jim Wilde Apr 1, 2013 12:14 PM (in response to AttilaHan)There are two things going on here.
1. When you change the capture date/time (Date Time Original), the change is immediately reflected in the EXIF portion of the Metadata panel in the Library module. Because this is a metadata change, the warning arrow appears on the thumbnail (if you have that set to show in the View Options)....and clicking on that arrow brings up the "Metadata changed, do you want to save to disk" dialog. Note that this happens when you do any kind of metadata change, not just changing the date/time. At that point you can either decide to write the metadata to disk, or not.....if you typically write your metadata changes to XMP I guess you'd say "Save", but if you don't then just ignore it. Of course if you say "Save" then Lightroom will do as requested and write the Metadata, if it's a DNG,JPEG,TIFF etc, the Metadata is written to the XMP section of the file header....but if it's a proprietary RAW then it's written to an XMP sidecar.
2. The second thing is that if you have the option set in the Catalog Settings to write date/time changes into proprietary raw files, then the change that you make is reflected in the Raw file.....this is a different change to the XMP update.
